74## AI Build Instructions
75 
76> **Read this section before writing any code.** The rules below
77> are non-negotiable. Every value used in the UI must come from this
78> file's frontmatter — never substitute, approximate, or invent new
79> colors, fonts, radii, or shadows. If a value is missing, ask the
80> user before adding one.
81 
82### 1 · Your role
83 
84You are building UI for a project that has adopted **Vellum Quiet** as its
85design system. Treat `DESIGN.md` as the single source of truth.
86Your job is to translate the user's product requirements into
87components and pages that look like they were designed by the same
88person who authored this file.
89 
90### 2 · Token compliance
91 
92- Pull every color, font family, radius, shadow, and spacing value
93  from the frontmatter at the top of this file.
94- Use semantic roles (e.g. `primary`, `accent`, `muted`) — never
95  hard-code hex values that bypass the system.
96- When a token can be expressed as a CSS variable, declare it once
97  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 recipes
102 
103Use these recipes verbatim when building the corresponding component.
104 
105#### Buttons
106 
107Four variants are defined. Pick one — never blend variants or invent a fifth.
108 
109- **Primary** — rounded shape, bg `#3E5A3A`, text `#FBF7EB`, border `1px solid #3E5A3A`, padding `12px 22px`, weight `500`.
110- **Secondary** — rounded shape, bg `#FBF7EB`, text `#1F1B14`, border `1px solid rgba(31, 27, 20, 0.16)`, padding `12px 22px`, weight `500`.
111- **Outline** — rounded shape, text `#1F1B14`, border `1px solid rgba(31, 27, 20, 0.20)`, padding `11px 21px`, weight `500`.
112- **Ghost** — rounded shape, text `#7A7264`, padding `11px 4px`, weight `500`.
113 
114Reach for **primary** as the single dominant CTA per screen.
115**Secondary** for the supporting action. **Outline** for tertiary
116actions in toolbars. **Ghost** for inline links and table actions.
117 
118#### Cards
119 
120- Background: `#FBF7EB`
121- Border: `1px solid rgba(31, 27, 20, 0.08)`
122- Shadow: `0 0 0 1px rgba(31, 27, 20, 0.08)`
123- Radius: `radius.lg` (`8px`)
124- Internal padding: `20px` for compact cards, `24–28px` for content cards.
125 
126#### Charts
127 
128- Bar/line variant: `line`
129- No gridlines — let the bars/lines carry the data.
130- Highlight strategy: `last` — emphasize a single bar/point per chart.
131- Use the declared palette in order: `#3E5A3A`.
132 
133#### Typography pairings
134 
135- **Display (`Inter Tight`)** — h1, h2, hero headlines, brand wordmarks.
136- **Body (`Inter`)** — paragraphs, labels, button text, form inputs.
137- **Mono (`JetBrains Mono`)** — code, eyebrows, metadata, numerals in tables.
138 
139### 4 · Hard constraints
140 
141Never do any of the following without explicit instruction from the user:
142 
143- Introduce a new color, font, radius, or shadow that isn't declared above.
144- Mix this system with another (e.g. don't paste in Material or Bootstrap defaults).
145- Use generic gradient defaults (purple→blue, peach→pink) — they break the system's voice.
146- Reach for emoji icons. Use a consistent icon library and size icons in line with body type.
147- Add motion that exceeds the system's restraint — keep transitions short (≤200ms) and subtle.
148 
149### 5 · Before you finish — verify
150 
151Run through this checklist for every screen you produce:
152 
153- [ ] Every color used appears in the Colors table above.
154- [ ] Headlines use the display font; body copy uses the body font.
155- [ ] Buttons match one of the declared variants exactly (shape, padding, weight).
156- [ ] Border-radius values come from `radius.sm` / `radius.md` / `radius.lg` / `radius.pill`.
157- [ ] Cards and dividers use the declared border + shadow tokens.
158- [ ] No values were invented; if you needed something missing, you stopped and asked.

162## Overview
163Vellum Quiet is calibrated to feel like a well-set page in a notebook. The canvas is warm vellum (distinctly not-white). Type is one humanist sans (Inter Tight) used at refined, restrained sizes — the hero stops at 4rem rather than pushing to 7-8rem. There are no shadows; depth comes from a single warm hairline. One deep moss-green accent does the entire chromatic work.
164 
165For writing apps, indie publishers, slow-content platforms, knowledge tools, anything that should feel considered and quiet rather than clamoring for attention.
166 
167## Color
168- **Ink #1F1B14** — primary text. Deep ink with a warm bias so it sits on vellum naturally.
169- **Warm graphite #7A7264** — secondary text.
170- **Soft graphite #A89F90** — captions, axis labels.
171- **Vellum #F4EEDF** — page canvas. Warm paper, distinctly not-white.
172- **Surface #FBF7EB** — card surface, a notch lighter and warmer than canvas.
173- **Moss #3E5A3A** — the only chromatic accent. Primary CTA, links, chart line.
174 
175The accent is a deep, slightly desaturated moss — not bright, not olive. It sits in the warm-paper world without breaking it.
176 
177## Typography
178**Inter Tight for display, Inter for body.** Same family lineage, different optical sizes.
179 
180| Role | Font | Size | Weight | Tracking |
181|------|------|------|--------|----------|
182| Hero | Inter Tight | 4rem | 500 | -0.03em |
183| H1 | Inter Tight | 2.375rem | 500 | -0.025em |
184| H2 | Inter Tight | 1.375rem | 500 | -0.012em |
185| Body | Inter | 1.0625rem | 400 | -0.003em / 1.7 |
186 
187The whole system runs at weight 500 for display — never 600 or 700. The restraint is the brand.
188 
189## Geometry
190- **Radii: 4 / 6 / 8.** Refined, neither sharp nor soft.
191- **No shadows.** A 1px ink hairline at 8% opacity is the only depth signal.
192- **Section gap: 112px** desktop, 72px mobile.
193- **12-column grid** with 24px gutters.
194 
195## Buttons
196- **Primary** — solid moss green, vellum label.
197- **Secondary** — surface vellum, ink label, warm hairline at 16% opacity.
198- **Outline** — bare hairline at 20% opacity.
199- **Ghost** — bare warm-graphite label, hover underline.
200 
201All buttons sit at 12px / 22px padding with 6px corners. The button is small and considered — never a CTA shouting for clicks.
202 
203## Cards
204Surface vellum on canvas, 1px ink hairline at 8% opacity, 6px corners, **no shadow**. Padding 28-32px. The card depth comes from the hairline alone.
205 
206## Charts & Data
207Single moss-green line at 1.5px stroke, no gridlines, end-of-line dot marker. Axis labels in soft graphite at 11px Inter. The chart reads as a notation, not a marketing graphic.
208 
209## Do's and Don'ts
210- ✅ Vellum canvas, never pure white. The warmth is the system.
211- ✅ Hero stops at 4rem. The system never shouts.
212- ✅ Display weight 500, never higher.
213- ✅ One chromatic accent — moss. Used sparingly.
214- ❌ No drop shadows. Hairline is the only depth.
215- ❌ No second chromatic accent. Moss stands alone.
216- ❌ No oversized type. The whole identity rests on restraint.
217- ❌ No pill buttons. Refined 6px corners only.

Aurora Haze

Warm grainy aurora applied with restraint — amber bleeds into coral and softens into violet, with real fractal-noise grain layered on top. Inter throughout, generous bone-white surfaces, and the gradient appears in exactly two places: the primary CTA and the featured hero tile. Everything else stays calm so the bloom carries.
