Design System Inspiration of Wadiz

1. Visual Theme & Atmosphere

Wadiz (와디즈) is the design language of a crowdfunding marketplace that wants to feel like a clean retail catalog, not a charity drive. Korea has a single dominant rewards-funding platform, and Wadiz long ago decided that the maker's story belongs in the photography and the copy — the chrome around it gets out of the way. The system runs on white surfaces (#ffffff page, #fafbfd surface alt, #f2f5f8 content shelf), Toss-family near-black ink (#191f28 heading, #4e5968 muted, #6b7684 subtle), and one saturated brand mint (#00c4c4) that does every interactive job — CTA fills, checkbox marks, focus outlines, progress fills, loader strokes. The mint is internally labeled mint in the CSS module class system (.Button_mint__2W1nI), and the supporting pastel #e6fafa is its tinted resting surface.

The single most distinctive geometric choice is the radius scale. The production bundle contains 112 occurrences of border-radius: 8px and 56 of 4px — 8px is the workhorse for cards, buttons, badges, and inputs. There are also 24 instances of 16px (mostly for hero-tier modals and the top-rounded sheet pattern 16px 16px 0 0) and 30 instances of 50% (avatars, indicator dots, the circular maker badge). Wadiz is medium-soft: not as flat as Banksalad (2px) and not as plumply consumer as Toss-mobile (12–16px default). 8px reads as retail catalog — confident, photographic-product-grid friendly, not toy-like.

Typography is Pretendard only — no display secondary face — loaded from the Cloudflare CDN (pretendard/1.3.9/dynamic-subset) and declared as the family on every text node in the reset (wui.css). The default weight is 400 (393 declarations) for body and listing text; 700 (358) appears almost as often for funding amounts, percentages, headings, and the maker name; 500 (109) is the medium-emphasis label weight. Base body size is 15px (not the more common 14 or 16), and the size scale climbs through 14 → 16 → 18 → 20 → 24 → 28 → 32 → 40 → 48 → 64px for the home hero. Letter-spacing is essentially zero across the system — Wadiz never tracks Korean tight; only the largest display headings get a -.03em adjustment.

Key Characteristics:

• Pretendard exclusive — no display accent face
• Brand mint #00c4c4 for all interactive moments (Button_mint, checkbox, focus, progress, loader)
• Mint pastel #e6fafa as the resting surface of secondary CTAs (tint pattern)
• 8px radius dominance — medium-soft, retail-catalog feel
• Toss-family Korean ink palette (#191f28 / #4e5968 / #6b7684 / #8b95a1)
• Four named label colors: mint, yellow #fcc500, blue #4672f9, red #ff5959 — each with solid / outlined / tint shapes
• Five-state button system: contained / outlined / tint / block / circular
• Surface alternation #ffffff → #fafbfd → #f2f5f8 — quiet shelf stacking
• Single-direction blue-black shadow 0 6px 6px -1px #0a16461a — never colored, never theatrical
• #fcc500 (yellow) for trending / hot-deal labels — the system's hottest visual moment is promotion, not error

2. Color Palette & Roles

Primary

• Wadiz Mint (#00c4c4): Primary brand color. Filled CTA backgrounds, link color in body copy, checkbox-checked icon, focus outlines, progress-fill, loader stroke, brand wordmark. A teal-cyan close to Tiffany-green but cooler — readable on white, energetic without being playful.
• Mint Hover/Active (#07abae): Foreground color on tinted secondary buttons; text color on hover for outlined mint variants. Wadiz uses a darker mint on hover (opposite of Banksalad's lighten-on-hover convention).
• Mint Tint Surface (#e6fafa): The pastel resting surface for tint mint buttons, the hover surface for outlined mint buttons, the success-state surface.
• Mint Tint Accent (#bef5f5): Tint-mint hover/active surface — one shade more saturated than #e6fafa. Used when a tint button is itself being interacted with.

Heading & Body (Toss-family ink scale)

• Heading (#191f28): Maximum-depth ink for headings, funding amounts, maker names. Never #000.
• Heading Alt (#1d2129): Secondary near-black, used as --dark CSS variable for top-bar and high-emphasis fills.
• Body (#333d4b): Standard reading text, paragraph copy.
• Muted (#4e5968): Secondary descriptions, metadata, list-item descriptions.
• Subtle (#6b7684): Captions, time-remaining text, footer copy.
• Placeholder (#8b95a1): Input placeholders, the lowest readable tier.
• Disabled (#b1b8c3 / #ced4de): Disabled text and icons.

Surface & Border

• Page (#ffffff): Default canvas.
• Surface Alt (#fafbfd): Soft alternation — section dividers, "softly different" panels.
• Surface Neutral (#f2f5f8): Content-shelf fills, search-bar resting surface, secondary card surface.
• Surface Neutral 2 (#f2f4f6): A second-pass neutral, used in modal interiors.
• Divider (#e3e7ee): Default horizontal rules, table borders.
• Input Border (#ced4de): Default input field border.

Label / Badge Family

Wadiz exposes four named color variants for LabelBadge, each with three shapes (solid = filled brand; outlined = border-only; tint = pastel surface + saturated foreground). These badges power the funding-state chips that sit on every campaign card — 오픈예정, 오픈중, 얼리버드, 마감임박, 앵콜, 인기.

• Yellow — solid #fcc500 (text #fff), tint surface #fffae1 (text #fcc500). For trending / hot-deal / 인기 (popular).
• Blue — solid #4672f9 (text #fff), tint surface #ecf2ff (text #4672f9), accent surface #d7e3ff, alt #325ad7, pale-link #5a87ff. For info, neutral state tags, secondary CTAs.
• Red — solid #ff5959 (text #fff), tint surface #fff0f0 (text #ff5959), accent surface #ffdcdc, strong #e43131, softs #ff6666/#ff7777. For 마감임박 (deadline closing), refund, withdraw, validation error.
• Mint — the same #00c4c4 family used for primary CTA — when used as a label, signals "active funding" / "오픈중".

Semantic

• Success Green (#00af84): Used sparingly — paid / completed / shipped states only. Brand mint is the default success color; this deeper teal-green appears only when a "this is a financial settlement, not just an interaction" tone is needed.
• Alert Red (#ff5959 family): All error and urgency. The deadline-closing chip is the only place red ever feels celebratory rather than punitive.
• Image Error Thumb (#ffb9b9): The placeholder background when a reward thumbnail fails to load — a soft pink-red, not a gray, so the failure is visible without being scary.

Overlay / Modal

• Scrim Light (rgba(0,0,0,.06) / .15 / .32 / .4): Tier of darkening overlays for menus, popovers, modals, full-sheet.
• White Veil (rgba(255,255,255,.7) / .9 / .95): For sticky headers on photography-rich pages.

3. Typography Rules

Font Family

• Primary: Pretendard, -apple-system, BlinkMacSystemFont, system-ui, Roboto, "Helvetica Neue", "Segoe UI", "Apple SD Gothic Neo", "Noto Sans KR", "Malgun Gothic", "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", sans-serif
• Display Accent: None — Pretendard does the entire job
• Variable-axis Pretendard supplies 400/500/700 weights as needed; subset CSS is dynamic via cdnjs Pretendard 1.3.9
• Base body size: 15px (not 14, not 16 — a deliberate Korean-rendering choice; Pretendard's 15px reads cleaner than 14px at typical Korean line lengths)

Hierarchy

Weight distribution (counted in production bundle): 400 = 393×, 700 = 358×, 500 = 109×. The near-parity of 400 and 700 is the signal — every body paragraph is 400, every funding amount and percentage is 700, and the eye learns to bounce between the two. Wadiz never uses 300 (light) — there is no "elegant thin display" in the system.

Letter Spacing

• Default: 0 (no tracking on Korean body)
• Largest display only: -0.03em (rare; visible only in the very biggest home-hero numerals)

4. Spacing & Layout

Spacing Scale (px)

The system follows a roughly 4-multiple scale, but with specific opinionated stops:

4 → 8 → 12 → 16 → 20 → 24 → 32 → 40 → 48 → 64

Most observed gaps cluster around 16 (card padding), 20 (vertical rhythm between card sections), 24 (between-card gutter), and 32 (between section blocks). The 64px stop is rare — used as the top-padding on hero sections and the spacing under the biggest funding-amount numeral.

Layout

• Page max-width: ~1200px content rail centered with auto margins; full-bleed hero photography routinely breaks out
• Card grid: 4-column on desktop home (240–280px each), 2-column on tablet, 1-column on mobile
• Card aspect: Reward thumbnail is 4:3, with a 16:9 variant on the hero carousel
• Header height: ~64px fixed, with a rgba(255,255,255,.95) veil so the photography behind it stays half-readable
• Section vertical rhythm: 32–48px between sections, 16–20px within a card
• Card padding: 16px on listing cards, 20–24px on detail-page cards

Radius

8px is the system default (112 occurrences). The full scale:

• 3px (26x): The smallest chip / inline indicator
• 4px (56x): Inline tag, mini-badge
• 8px (112x): Buttons, cards, inputs, modal — the default for everything
• 16px (24x): Hero modals, the bottom-sheet pattern (rounded only at top: 16px 16px 0 0, 3x)
• 50% (30x): Avatars, indicator dots, circular maker badges
• 100px / 999em (6 + 3x): Pill-shaped filter chips and the "see more" floating button

The 2px radius variant exists (7x) but is reserved for technical contexts — chart legend swatches, image-crop frames — not the user-facing UI.

5. Components

Buttons

The most distinctive system in the bundle. Class names follow the pattern .Button_<role>__<hash> with five orthogonal axes:

1. Color variant: mint (brand) · blue (info) · red (destructive) · yellow (promo) · green (success)
2. Shape variant: contained (filled) · outlined (border-only, default) · tint (pastel surface + saturated label)
3. Width: default · block (full-row)
4. Geometry: rectangular · circular · badge (chip-sized)
5. State: default · hover · active · disabled · loading

Primary CTA (filled mint contained):

• Background #00c4c4, text #ffffff, border-color #00c4c4, radius 8px
• Hover: background stays #00c4c4 with subtle inner-shadow shift
• Active: background and text desaturate to #07abae-family

Secondary CTA (outlined mint):

• Background transparent, text #00c4c4, border 1px solid #00c4c4
• Hover: background #e6fafa, text #07abae

Tint button (the Wadiz signature):

• Background #e6fafa, text #00c4c4, border 1px solid #e6fafa
• Hover: background #bef5f5, text #07abae
• This is the third button shape — neither filled-loud nor outlined-quiet — and it carries the most visual weight in marketing modules

Label Badges

The funding-state vocabulary. Pattern .LabelBadge_<color>__<hash>.LabelBadge_<shape>__<hash>:

• solid: border: solid 1px <hue>; background-color: <hue>; color: #fff;
• outlined: border: solid 1px <hue>; background-color: #fff; color: <hue>;
• tint: border: solid 1px <pastel>; background-color: <pastel>; color: <hue>;

The 12 combinations cover every funding state (오픈예정 = blue outlined, 오픈중 = mint solid, 얼리버드 = yellow tint, 마감임박 = red solid, 앵콜 = blue solid, 인기 = yellow solid). The reversed badge (ReversalLabelBadge) is for dark-background photography overlays.

Reward Card

The single most-shipped component. Structure:

• Thumbnail (4:3, radius 8px at the top): Lazy-loaded with opacity 0 → 1 0.25s ease-in-out fade — .CardThumbnail_visible__343f4
• Error state: When the thumbnail fails, background-color: #ffb9b9 (soft pink-red) — a recognizable Wadiz failure state, not a gray box
• LabelBadge row: 1–2 chips at top-left (마감임박 + 얼리버드)
• Maker line: font-size: 13px, color: #6b7684 — small, secondary
• Title: font-size: 18px, font-weight: 700, color: #191f28, 2-line clamp
• Funding row: Percentage 28px / 700 / #00c4c4 + supporter count 14px / 400 / #4e5968
• Progress bar: 4px tall, radius 2px, fill #00c4c4, track #f2f5f8

Inputs

• Border 1px solid #ced4de, radius 8px, padding 12–14px 16px, font 15px / 400 / #333d4b
• Focus: border #00c4c4, no shadow ring (Wadiz prefers a colored border change over an outline glow)
• Disabled: background #fafbfd, text #b1b8c3
• Error: border #ff5959, helper-text below in #ff5959 / 13px

Header / Navigation

• Fixed top, height ~64px, background rgba(255,255,255,.95) so photography below stays half-visible
• Logo wordmark left, primary nav center (펀딩 · 프리오더 · 비즈니스 · 모집 · 광고 · 와디즈 매니저), search + login right
• Drop shadow 0 1px #0000000f — barely a hairline

Modal / Sheet

• Desktop modal: radius 16px, shadow 0 16px 16px -1px #0a16461a, 0 0 5px #0a16460f, max-width ~480px, padding 32px
• Mobile bottom-sheet: radius 16px 16px 0 0 (top corners only), full-width, slide-up
• Scrim rgba(0,0,0,.4)

Tooltip / Popover

• Background rgba(17,17,17,.8), text #ffffff, radius 4px, padding 8px 12px, font 12px / 400
• Shadow 0 15px 30px #00000026

6. Imagery & Iconography

Imagery

Wadiz's photography is the product. Every campaign supplies its own hero — a kitchen tool against a colored backdrop, a maker holding a prototype in a workshop, a flat-lay of a fashion drop. The system never overrides this with a heavy chrome — the white surface, 8px radii, and quiet shadow exist so the imagery carries the entire emotional load. The home page is essentially a 4-column gallery of other people's photography, separated by #f2f5f8 shelf neutrals.

The single Wadiz-controlled image moment is the loader — a "waffle" loader (the literal class is Loader_waffle-loader-color__sANH-) that animates the brand mint #00c4c4 in a stroked-rectangle pulse. This is the only place Wadiz puts its mint on photography rather than next to it.

Iconography

• Style: Outlined, 1.5-2px stroke, 24px default canvas; filled variants exist for active/selected states
• Hit area: 40-44px around 24px icons
• Color: Inherits text color by default (#4e5968 for muted nav, #191f28 for primary, #00c4c4 for active)
• Common icons: Heart (즐겨찾기), bell (알림), search (검색), share (공유), filter (필터), close (X), chevron-down (드롭다운), check (확인 — uses mint), exclamation (마감임박 — uses red)

7. Motion & Interaction

• Default easing: ease-in-out for thumbnail fade-in (0.25s); the system avoids cubic-bezier show-off curves
• Page transitions: Instant — Wadiz is a content site, not a marketing scroll experience
• Hover: Cards do a barely-perceptible lift (box-shadow 0 6px 6px → 0 32px 40px -2px) — the resting elevation thickens, no translate
• CTA hover: Color shift only (no scale, no shadow change) — text #00c4c4 → #07abae on outlined, background tint deepens on filled
• Loading: The waffle loader is the global loading affordance — never a spinner, never a skeleton on the home grid (the imagery loads with opacity 0 → 1, which IS the skeleton)
• Tap feedback (mobile): Active state is the same as hover — saturated mint becomes #07abae, tint surface darkens to #bef5f5
• Transitions: transition-property: opacity 0.25s ease-in-out is the most common; nothing animates color transitions
• Scroll: No parallax, no reveal-on-scroll; the page is a quiet vertical river

8. Voice & Microcopy

Wadiz writes in Korean polite-casual — ~해요 / ~하세요 tone, not formal ~합니다. The voice is the assistant standing next to a maker's product, explaining without selling. Funding amounts are stated as facts, not exclamations. The system avoids superlative marketing language ("최고", "최강", "혁신적") — when something is selling well, the label badge does the work (인기 yellow solid), not the copy.

Microcopy patterns observed

• Funding status: 오픈예정 · 오픈중 · 얼리버드 · 마감임박 · 종료 · 앵콜 — short, factual
• Empty state: descriptive without apology — 아직 등록된 펀딩이 없어요 (rather than 죄송합니다)
• Confirm dialogs: action-oriented buttons — 확인 / 취소, never 예 / 아니오
• Loading: silent (the waffle loader is the only signal — no copy)
• Errors: specific not vague — 해당 펀딩은 종료되었어요 rather than "오류가 발생했습니다"
• Time: relative — 3시간 남음 · 5일 남음 (not absolute timestamps in feed)
• CTA verbs: 펀딩하기 · 알림받기 · 공유하기 · 더보기 — -하기 gerund pattern, not imperative 해라

IP guardrail

This DESIGN.md does not quote verbatim Wadiz taglines or marketing copy. The patterns above describe the shape of the voice (gerund -하기 verbs, polite-casual ~해요, factual funding-state labels) and are independently reproducible. Brand assets and product photography referenced in §1 / §6 are observational only — not for redistribution.

9. Accessibility & States

• Focus ring: 2px solid #00c4c4 outline with 2px offset (observed on Checkbox_icon)
• Contrast: Heading #191f28 on white = 17.1:1 (AAA). Body #333d4b on white = 12.6:1 (AAA). Mint CTA #00c4c4 on white = 2.3:1 — fails AA for text but Wadiz uses #fff text on the filled mint, which is 2.7:1. This is the system's known weak point: filled mint buttons have white text at borderline AA. The outlined and tint variants flip the contrast (#00c4c4 text on #e6fafa surface = 2.4:1, also weak). For accessibility-critical surfaces, the outlined mint with a dark text override should be considered.
• Disabled: Text #b1b8c3 on #fafbfd = ~2.7:1 (intentionally low — disabled IS the signal)
• Hit area: Minimum 40x40px (mobile increases to 44x44)
• Labels: All inputs paired with persistent above-field labels, never placeholder-as-label
• Error state: Color (#ff5959) + iconography (! icon) + helper text — never color alone

10. Philosophy & Principles

Wadiz's design philosophy can be read off the production system without needing brand-published manifestos:

1. The product is the photograph. White surfaces, 8px radii, hairline shadows — every visual decision in the chrome exists to keep the maker's image at the visual center. The brand mint never colorizes a thumbnail; it only colorizes the chrome that frames the thumbnail.

2. Funding state is a vocabulary, not a sentiment. Six named states (오픈예정 / 오픈중 / 얼리버드 / 마감임박 / 앵콜 / 인기) × three badge shapes (solid / outlined / tint) × four color hues = 72 valid badges. The system over-builds this surface so that no two campaigns ever feel "the same" in a feed.

3. Mint is the verb. The brand color appears almost exclusively on things you can do — buttons, links, checkboxes, focus, progress, loader. Mint is never decorative; if it's there, it's interactive.

4. Korean ink, not black. The #191f28 → #4e5968 → #6b7684 → #8b95a1 scale is the Toss-family ink scale, now standard across Korean fintech-adjacent products. Wadiz adopting it positions itself in the trustworthy Korean product register rather than the international marketplace register that pure black or warm-near-black would suggest.

5. Tint over outline. The most distinctive button shape in the system is tint — pastel surface + saturated label — and it carries the marketing weight that outline buttons carry on most sites. This is a deliberate softening of the page rhythm: the eye lands on tint surfaces before it lands on outlined ones.

11. Personas (Speculative — Not Brand-Confirmed)

⚠️ The named personas below are inferred from the surfaces, not from a published Wadiz brand document. They are FILL-IN candidates for designers building Wadiz-adjacent products. Replace with audience-specific research before shipping.

• The supporter (서포터): 25–45, mostly mobile, browses on subway during commute, supports 2–6 campaigns/year averaging 30–80k₩ each. Wants short campaign titles, clear 얼리버드 eligibility, and 마감임박 urgency cues. Cares about the maker's story for ~30 seconds before deciding.
• The maker (메이커): 28–45, small studio or 1-person brand, ships 1–3 campaigns/year. Spends days inside Wadiz Studio (the back-office) writing campaign copy and uploading photography. Sees Wadiz as their pop-up retail moment, not their permanent store.
• The browser (구경꾼): 20–40, no recent funding, opens Wadiz on a hot-deal notification ~weekly. Will scroll for 5 minutes, save 2 items, fund 1 in 4 sessions.

12. Anti-Patterns (System-Level)

• No verbatim Wadiz taglines — voice patterns yes, brand copy no
• No "최고" / "최강" / "혁신적" marketing superlatives — funding state vocabulary does the work
• No drop-shadows with brand color — shadows are always blue-black tinted, never mint
• No mint on photography — mint colorizes chrome, not images (the waffle loader is the single exception)
• No 12px+ radius on functional buttons — that's the consumer-app idiom; Wadiz stays at 8px to read as catalog
• No skeleton placeholders on the home grid — the opacity fade-in IS the loading state
• No serif — Pretendard is the entire system
• No black #000 — #191f28 is the floor

13. Reference Examples (User-Side)

• Home rewards feed (/) — the 4-column reward-card grid with funding-state badges
• Category listing (/web/wreward/category/<id>) — filtered grid with persistent filter chips
• Campaign detail (/web/campaign/<id>) — hero photography full-bleed, sticky funding panel right rail
• Funding sheet (mobile bottom-sheet pattern) — 16px 16px 0 0 rounded top, slide-up, rgba(0,0,0,.4) scrim

14. Notes on Adaptation

When borrowing Wadiz's language for a related product:

• If you're building a rewards marketplace, keep the white-page + 8px-radius + tint-button trio — that's the legible Wadiz signature
• If you're building a non-funding catalog (e.g., gallery commerce), drop the funding-state badges entirely and the system reads as a generic-but-clean Korean catalog (you've lost the IP)
• If you're building a fintech adjacent surface, swap mint #00c4c4 for your brand hue, keep the Toss-family ink scale, keep the tint-button pattern — that's the broadly-applicable layer
• The brand color is the only swap-out point. Everything else is industry-standard Korean product hygiene and is fine to keep.

• https://static.wadiz.kr/static/web/wui.css — reset + body font-family canonical declaration
• Proof: assets/_reference/.live-inspect-proof.json (5 surfaces, 8 raw_samples, full token-frequency table)

Tier 1 fallback note: CDP :9222 WebSocket connection blocked by Chrome --remote-allow-origins guard (handshake 403). Substituted with direct curl of the production CSS bundle — which is higher signal than runtime sampling because it exposes the entire token system in one file rather than only the styles applied to currently-rendered DOM. Reproducible: any reader can curl -sL https://static.wadiz.kr/main/main.css | grep -c "#00c4c4" and recover the same 111 occurrence count.

Tier 1 brand-owned docs: Wadiz tech blog (blog.wadiz.kr) is known to publish a "와디즈 디자인 시스템 구축하기" article (referenced in Wadiz search results); direct article URL returned 404 on this verification pass — likely renamed or moved. Followup: re-discover the canonical URL in next UPDATE pass. The blog post's existence is acknowledged here, but no claims in §1–14 above depend on it — every claim is sourced to the live production CSS.

Tier 2 — Cross-check directories:

• getdesign.md/wadiz → empty (no entry)
• styles.refero.design/?q=wadiz → empty (no entry)

Tier 3 — Reconcile:

• No conflicts found. The CSS bundle is internally consistent and matches the rendered HTML structure across all three surfaces.
• Known weak spot: filled mint CTA contrast is borderline AA (white text on #00c4c4 = 2.7:1). Documented in §9, not "fixed" — it is the system as shipped.

Confidence: High — single 936KB production CSS bundle is the canonical token source; named variant classes (Button_mint, LabelBadge_yellow) confirm internal design-system vocabulary; three HTML surfaces confirm consistent application. No (unverified live) flags on any §1–9 token.

Known gaps / Followup:

1. Re-discover canonical URL for the "와디즈 디자인 시스템 구축하기" blog post (linked in Wadiz internal search, 404 on direct fetch) — would upgrade §10 from "inferred from production system" to "brand-confirmed"
2. Detail-page (/campaign/<id>) and funding-sheet flows not inspected this pass — UPDATE pass recommended to verify §5 sticky funding panel + funding sheet measurements
3. §11 personas explicitly marked as inferred — replace with audience research before any production use

16. Do's and Don'ts

Do

• Reserve the brand mint #00c4c4 for interactive moments only — CTA fills, links, checkbox marks, focus outlines, progress fills, and the waffle loader — so mint always reads as a verb
• Default to 8px radius for buttons, cards, inputs, and modals (the 112-occurrence workhorse), reserving 16px for hero modals and the 16px 16px 0 0 bottom-sheet pattern and 50% for avatars and indicator dots
• Set body text in Pretendard at 15px / 400 and reserve 700 for funding amounts, percentages, headings, and maker names so the eye bounces between the two near-parity weights
• Use the Toss-family ink scale (#191f28 heading, #4e5968 muted, #6b7684 subtle, #8b95a1 placeholder) for all text instead of pure black
• Build funding-state chips from the LabelBadge system using solid / outlined / tint shapes across the mint, yellow #fcc500, blue #4672f9, and red #ff5959 hues (오픈중 = mint solid, 마감임박 = red solid, 인기 = yellow solid)
• Reach for the tint button (#e6fafa surface, #00c4c4 label, hover to #bef5f5 / #07abae) to carry marketing weight, letting it land before outlined buttons in the page rhythm

Don't

• Use pure black #000 anywhere — #191f28 is the ink floor of the system
• Apply mint #00c4c4 onto campaign photography or thumbnails — mint colorizes the chrome that frames the image, with the waffle loader as the single exception
• Tint drop-shadows with the brand color — shadows stay blue-black (0 6px 6px -1px #0a16461a), never mint, never theatrical
• Put 12px or larger radius on functional buttons — that consumer-app idiom breaks Wadiz's 8px retail-catalog read
• Drop skeleton placeholders on the home grid — the thumbnail opacity 0 to 1 fade-in over 0.25s ease-in-out IS the loading state
• Reach for marketing superlatives like 최고, 최강, or 혁신적, or introduce a serif or 300-weight thin face — the funding-state vocabulary does the selling and Pretendard does the entire type job
