An architecture studio's monograph rendered in HTML. Cormorant Garamond at oversized scale for project titles, Inter for body, concrete-grey surfaces with one warm terracotta accent reserved for the project number. Built for architecture firms, design studios, and portfolio sites where each project deserves its own page.
A complete design system, ready for your AI coding agent. Every primitive, token, and pattern below is generated straight from DESIGN.md — drop the file in your project and ship matching UI in minutes.
Prose-first token file — decisions live next to their reasoning.
Fine micro-scale (1–5px) for pills, editorial scale (12–21px) for the grid.
The system's own radius tokens — sm for chips and inputs, md for buttons, lg for cards, pill for fully-rounded CTAs.

Every value used in the UI must come from this82> file's frontmatter — never substitute, approximate, or invent new83> colors, fonts, radii, or shadows. If a value is missing, ask the84> user before adding one.85 86### 1 · Your role87 88You are building UI for a project that has adopted **Atrium Folio** as its89design system. Treat `DESIGN.md` as the single source of truth.90Your job is to translate the user's product requirements into91components and pages that look like they were designed by the same92person who authored this file.93 94### 2 · Token compliance95 96- Pull every color, font family, radius, shadow, and spacing value97 from the frontmatter at the top of this file.98- Use semantic roles (e.g. `primary`, `accent`, `muted`) — never99 hard-code hex values that bypass the system.100- When a token can be expressed as a CSS variable, declare it once101 in your global stylesheet and reference it everywhere downstream.102- The Google Fonts `<link>` is provided in the Typography section.103 Add it to `<head>` before any component renders.104 105### 3 · Component recipes106 107Use these recipes verbatim when building the corresponding component.108 109#### Buttons110 111Four variants are defined. Pick one — never blend variants or invent a fifth.112 113- **Primary** — sharp shape, bg `#1c1a17`, text `#e9e6df`, padding `12px 24px`, weight `500`, uppercased.114- **Secondary** — sharp shape, text `#1c1a17`, border `1px solid #1c1a17`, padding `12px 24px`, weight `500`, uppercased.115- **Outline** — sharp shape, text `#1c1a17`, border `1px solid rgba(28,26,23,0.18)`, padding `12px 24px`, weight `500`, uppercased.116- **Ghost** — sharp shape, text `#6b675f`, padding `12px 18px`, weight `500`, uppercased.117 118Reach for **primary** as the single dominant CTA per screen.119**Secondary** for the supporting action. **Outline** for tertiary120actions in toolbars. **Ghost** for inline links and table actions.121 122#### Cards123 124- Background: `#e9e6df`125- Border: `1px solid rgba(28,26,23,0.10)`126- Shadow: `none`127- Radius: `radius.lg` (`0px`)128- Internal padding: `20px` for compact cards, `24–28px` for content cards.129 130#### Tabs131 132Variant: `underline`. Flat row of labels. Active tab gets a 2px underline in the accent color — no fill.133 134#### Charts135 136- Bar/line variant: `thin-bars`137- No gridlines — let the bars/lines carry the data.138- Highlight strategy: `single` — emphasize a single bar/point per chart.139 140#### Typography pairings141 142- **Display (`Cormorant Garamond`)** — h1, h2, hero headlines, brand wordmarks.143- **Body (`Inter`)** — paragraphs, labels, button text, form inputs.144- **Mono (`JetBrains Mono`)** — code, eyebrows, metadata, numerals in tables.145 146### 4 · Hard constraints147 148Never do any of the following without explicit instruction from the user:149 150- Introduce a new color, font, radius, or shadow that isn't declared above.151- Mix this system with another (e.g. don't paste in Material or Bootstrap defaults).152- Use generic gradient defaults (purple→blue, peach→pink) — they break the system's voice.153- Reach for emoji icons. Use a consistent icon library and size icons in line with body type.154- Add motion that exceeds the system's restraint — keep transitions short (≤200ms) and subtle.155 156### 5 · Before you finish — verify157 158Run through this checklist for every screen you produce:159 160- [ ] Every color used appears in the Colors table above.161- [ ] Headlines use the display font; body copy uses the body font.162- [ ] Buttons match one of the declared variants exactly (shape, padding, weight).163- [ ] Border-radius values come from `radius.sm` / `radius.md` / `radius.lg` / `radius.pill`.164- [ ] Cards and dividers use the declared border + shadow tokens.165- [ ] No values were invented; if you needed something missing, you stopped and asked.166 167---168 169## 1. Atmosphere170 171Atrium Folio is what an architecture studio's monograph looks like when you scroll it. The page surface is concrete-grey `#e9e6df` — never white, never warm. Project titles run in Cormorant Garamond at 128px, weight 400 — the high-contrast didone proportions earning their drama from sheer scale, never weight. Body sits in Inter at 17px on a 1.7 leading, two-column when there's room. Project numbers, dates, and addresses run in JetBrains Mono with 0.10em uppercase tracking. The single accent is terracotta `#a8533d` that appears only as the colored project number ("№ 04") and as the 1px underline beneath the active project in the index.172 173The discipline is in the proportion: massive serif headlines on concrete, mono marginalia, and one warm earthy accent on two specific gestures.174 175**Signature moves**176- Cormorant Garamond at 128px, weight 400 — drama through scale, never weight177- Concrete-grey surface `#e9e6df` — never white, never beige178- Terracotta `#a8533d` only as the project number ("№ 04") and active project underline179- Sharp 0px radius everywhere — architectural precision180- All UI labels uppercase 0.10em tracking — wide spacing reads as monograph caption181- Two-column body where space allows — print rhythm182 183## 2. Palette184 185### Surfaces186- **Concrete** `#e9e6df` — page background (warm grey-brown)187- **Concrete Lift** `#dcd9d2` — section bands, secondary surfaces188- **Hairline** `rgba(28,26,23,0.10)` — every divider189 190### Ink191- **Ink** `#1c1a17` — text, headings, primary CTA fill192- **Ink 50** `#6b675f` — secondary text, mono marginalia193 194### Accent195- **Terracotta** `#a8533d` — project number, active project underline, chart highlight bar196- That is the only color in the system.197 198## 3.
