Treat `DESIGN.md` as the single source of truth.86Your job is to translate the user's product requirements into87components and pages that look like they were designed by the same88person who authored this file.89 90### 2 · Token compliance91 92- Pull every color, font family, radius, shadow, and spacing value93 from the frontmatter at the top of this file.94- Use semantic roles (e.g. `primary`, `accent`, `muted`) — never95 hard-code hex values that bypass the system.96- When a token can be expressed as a CSS variable, declare it once97 in your global stylesheet and reference it everywhere downstream.98- The Google Fonts `<link>` is provided in the Typography section.99 Add it to `<head>` before any component renders.100 101### 3 · Component recipes102 103Use these recipes verbatim when building the corresponding component.104 105#### Buttons106 107Four variants are defined. Pick one — never blend variants or invent a fifth.108 109- **Primary** — rounded shape, bg `#3d3a8a`, text `#f4f2fb`, padding `11px 22px`, weight `600`.110- **Secondary** — rounded shape, bg `rgba(255,255,255,0.55)`, text `#1a1830`, border `1px solid rgba(26,24,48,0.10)`, padding `11px 22px`, weight `500`.111- **Outline** — rounded shape, text `#1a1830`, border `1px solid rgba(26,24,48,0.18)`, padding `11px 22px`, weight `500`.112- **Ghost** — rounded shape, text `#6b6987`, padding `11px 16px`, weight `500`.113 114Reach for **primary** as the single dominant CTA per screen.115**Secondary** for the supporting action. **Outline** for tertiary116actions in toolbars. **Ghost** for inline links and table actions.117 118#### Cards119 120- Background: `#eeeaf5`121- Border: `1px solid rgba(255,255,255,0.55)`122- Shadow: `rgba(26,24,48,0.05) 0 1px 2px, rgba(26,24,48,0.04) 0 8px 24px -8px`123- Radius: `radius.lg` (`22px`)124- Internal padding: `20px` for compact cards, `24–28px` for content cards.125 126#### Tabs127 128Variant: `pill`.

Use a consistent icon library and size icons in line with body type.150- Add motion that exceeds the system's restraint — keep transitions short (≤200ms) and subtle.151 152### 5 · Before you finish — verify153 154Run through this checklist for every screen you produce:155 156- [ ] Every color used appears in the Colors table above.157- [ ] Headlines use the display font; body copy uses the body font.158- [ ] Buttons match one of the declared variants exactly (shape, padding, weight).159- [ ] Border-radius values come from `radius.sm` / `radius.md` / `radius.lg` / `radius.pill`.160- [ ] Cards and dividers use the declared border + shadow tokens.161- [ ] No values were invented; if you needed something missing, you stopped and asked.162 163---164 165## 1. Atmosphere166 167Atelier Glass is a studio interface built around real glassmorphism. The page surface is a soft tonal lavender-bone `#eeeaf5` — never white, never grey. Cards are frosted glass: `background: rgba(255,255,255,0.55)`, `backdrop-filter: blur(20px)`, with a 1px white inner border at 55% opacity that picks up the page tint and reads as light bouncing through the pane. Display headlines run in Spectral 500 at 80px with one italic word per headline — the calligraphic accent through frosted glass. Body sits in Plus Jakarta Sans at 17px on a 1.62 leading. The single accent is deep indigo `#3d3a8a` reserved for the primary CTA, the active panel ring, and the focus state — never as a background, never as a fill.168 169The discipline is in the glass behaviour: every elevated surface uses `backdrop-filter: blur(20px) saturate(1.4)` with a 55% white tint — the saturation lift is what makes the lavender bleed through and reads as actual frosted glass, not as a grey overlay.170 171**Signature moves**172- Real `backdrop-filter: blur(20px) saturate(1.4)` on every elevated card173- Lavender-bone surface `#eeeaf5` — the tint that bleeds through the glass IS the system174- Spectral 500 italic accent on one word per headline — the calligraphic moment175- Indigo `#3d3a8a` exclusively on primary CTA + active panel ring + focus state176- 1px inner border at 55% white on every glass card — the bouncing-light edge177 178## 2.
