75## AI Build Instructions
76 
77> **Read this section before writing any code.** The rules below
78> are non-negotiable. Every value used in the UI must come from this
79> file's frontmatter — never substitute, approximate, or invent new
80> colors, fonts, radii, or shadows. If a value is missing, ask the
81> user before adding one.
82 
83### 1 · Your role
84 
85You are building UI for a project that has adopted **Champagne Foundry** as its
86design system. Treat `DESIGN.md` as the single source of truth.
87Your job is to translate the user's product requirements into
88components and pages that look like they were designed by the same
89person who authored this file.
90 
91### 2 · Token compliance
92 
93- Pull every color, font family, radius, shadow, and spacing value
94  from the frontmatter at the top of this file.
95- Use semantic roles (e.g. `primary`, `accent`, `muted`) — never
96  hard-code hex values that bypass the system.
97- When a token can be expressed as a CSS variable, declare it once
98  in your global stylesheet and reference it everywhere downstream.
99- The Google Fonts `<link>` is provided in the Typography section.
100  Add it to `<head>` before any component renders.
101 
102### 3 · Component recipes
103 
104Use these recipes verbatim when building the corresponding component.
105 
106#### Buttons
107 
108Four variants are defined. Pick one — never blend variants or invent a fifth.
109 
110- **Primary** — rounded shape, bg `linear-gradient(180deg, #E6CC92 0%, #C9A96A 50%, #A88848 100%)`, text `#1F1A14`, border `1px solid rgba(122, 89, 45, 0.35)`, padding `12px 26px`, weight `500`, shadow `0 8px 20px -10px rgba(122, 89, 45, 0.40), inset 0 1px 0 rgba(255, 245, 220, 0.55), inset 0 -1px 0 rgba(122, 89, 45, 0.20)`.
111- **Secondary** — rounded shape, bg `#FBF7EE`, text `#1F1A14`, border `1px solid rgba(122, 107, 88, 0.25)`, padding `12px 26px`, weight `500`.
112- **Outline** — rounded shape, text `#7A6B58`, border `1px solid rgba(122, 107, 88, 0.40)`, padding `11px 24px`, weight `500`.
113- **Ghost** — rounded shape, text `#7A6B58`, padding `11px 4px`, weight `500`.
114 
115Reach for **primary** as the single dominant CTA per screen.
116**Secondary** for the supporting action. **Outline** for tertiary
117actions in toolbars. **Ghost** for inline links and table actions.
118 
119#### Cards
120 
121- Background: `#FBF7EE`
122- Border: `1px solid rgba(122, 107, 88, 0.15)`
123- Shadow: `0 1px 2px rgba(31, 26, 20, 0.04), 0 0 0 1px rgba(122, 107, 88, 0.08)`
124- Radius: `radius.lg` (`6px`)
125- Internal padding: `20px` for compact cards, `24–28px` for content cards.
126 
127#### Charts
128 
129- Bar/line variant: `line`
130- No gridlines — let the bars/lines carry the data.
131- Highlight strategy: `last` — emphasize a single bar/point per chart.
132- Use the declared palette in order: `#C9A96A`, `#A88848`, `#7A6B58`.
133 
134#### Typography pairings
135 
136- **Display (`Cormorant Garamond`)** — h1, h2, hero headlines, brand wordmarks.
137- **Body (`Inter`)** — paragraphs, labels, button text, form inputs.
138- **Mono (`JetBrains Mono`)** — code, eyebrows, metadata, numerals in tables.
139 
140### 4 · Hard constraints
141 
142Never do any of the following without explicit instruction from the user:
143 
144- Introduce a new color, font, radius, or shadow that isn't declared above.
145- Mix this system with another (e.g. don't paste in Material or Bootstrap defaults).
146- Use generic gradient defaults (purple→blue, peach→pink) — they break the system's voice.
147- Reach for emoji icons. Use a consistent icon library and size icons in line with body type.
148- Add motion that exceeds the system's restraint — keep transitions short (≤200ms) and subtle.
149 
150### 5 · Before you finish — verify
151 
152Run through this checklist for every screen you produce:
153 
154- [ ] Every color used appears in the Colors table above.
155- [ ] Headlines use the display font; body copy uses the body font.
156- [ ] Buttons match one of the declared variants exactly (shape, padding, weight).
157- [ ] Border-radius values come from `radius.sm` / `radius.md` / `radius.lg` / `radius.pill`.
158- [ ] Cards and dividers use the declared border + shadow tokens.
159- [ ] No values were invented; if you needed something missing, you stopped and asked.

163## Overview
164Champagne Foundry is a warm metallic premium system. Cream paper canvas, deep ink type in a high-contrast serif, and one machined gesture: a brushed champagne primary CTA with a top-edge gloss and a bottom-edge shadow that reads as lit metal.
165 
166For high-end consumer brands, watchmakers, private banking, concierge platforms, hospitality. Premium without ostentation — restraint is the whole point.
167 
168## The Metallic Gesture
169The primary button is the system's signature. It uses a vertical 3-stop gradient that mimics a lit brushed surface:
170 
171```css
172background: linear-gradient(180deg, #E6CC92 0%, #C9A96A 50%, #A88848 100%);
173border: 1px solid rgba(122, 89, 45, 0.35);
174box-shadow:
175  0 8px 20px -10px rgba(122, 89, 45, 0.40),
176  inset 0 1px 0 rgba(255, 245, 220, 0.55),
177  inset 0 -1px 0 rgba(122, 89, 45, 0.20);
178```
179 
180The inner top-edge highlight is what reads as "polished." Without it the button looks flat. The inner bottom-edge shadow gives the metal weight. Both must be present.
181 
182**Where it appears:**
183- The primary CTA fill.
184- An optional thin horizontal divider beneath the hero (1px gradient line).
185 
186**Where it never appears:**
187- Body text. Card fills. Backgrounds. Logos. Any second button on the page.
188 
189## Color
190- **Ink #1F1A14** — primary text.
191- **Bronze #7A6B58** — secondary text, refined captions.
192- **Champagne #C9A96A** — the accent endstop.
193- **Cream Paper #F4EFE6** — page canvas.
194- **Warm Paper #FBF7EE** — card surface.
195 
196The system is monochromatic-warm. There is no second hue. Restraint of palette is what allows the metal to feel precious.
197 
198## Typography
199- **Display: Cormorant Garamond 400** at 5.5rem with -2.5% tracking. High-contrast serif, never bolded above 500.
200- **Body: Inter 400** at 1rem with **1.7 leading**.
201- Italic Cormorant for emphasis inside hero headlines (one word per hero).
202 
203| Role | Font | Size | Weight | Tracking |
204|------|------|------|--------|----------|
205| Hero | Cormorant Garamond | 5.5rem | 400 | -0.025em |
206| H1 | Cormorant Garamond | 3.25rem | 400 | -0.02em |
207| H2 | Cormorant Garamond | 1.625rem | 500 | -0.01em |
208| Body | Inter | 1rem | 400 | 0 / 1.7 |
209 
210## Geometry
211- **Radii: 2 / 4 / 6.** Architectural restraint. The metal looks expensive at 4px; at 12px it looks cheap.
212- **Section gap: 160px** desktop, 96px mobile. Air around the metal is mandatory.
213- **Card padding: 40px** minimum.
214 
215## Buttons
216- **Primary** — brushed champagne with the full gloss/shadow stack. The single most precious element on the page.
217- **Secondary** — warm paper, 25% bronze hairline.
218- **Outline** — transparent with a 40% bronze hairline.
219- **Ghost** — bare bronze label, hover underline.
220 
221All four are softly rounded at 4px. The rest is restraint.
222 
223## Cards
224Warm paper surface, 1px bronze hairline at 15%, a 1px shadow at 4%. Radius 6px. Cards never lift — the page is a layered paper composition, not a stack of floating tiles.
225 
226## Charts & Data
227A single 1.5px champagne line over the cream canvas, no gridlines, no fills. A champagne dot at the latest reading. The chart should feel like a hand-engraved plot.
228 
229## Do's and Don'ts
230- ✅ The metallic gradient appears once per page — the primary CTA. That's it.
231- ✅ Always include the inner top-edge highlight + inner bottom-edge shadow. Without them the metal dies.
232- ✅ Cormorant 400 for display — never bolded above 500. The serif's contrast is the elegance.
233- ✅ Italic Cormorant on one accent word per hero, max.
234- ❌ No second metallic surface. No silver, no rose-gold, no chrome.
235- ❌ No drop shadows beyond the warm bronze underglow on the primary CTA.
236- ❌ No pills. No 12px+ radii. The metal needs sharp edges to read as crafted.
237- ❌ No saturated chromatic accents. The system is warm-monochrome.
