76# Hemlock Paper

78## AI Build Instructions
79 
80> **Read this section before writing any code.** The rules below
81> are non-negotiable. Every value used in the UI must come from this
82> file's frontmatter — never substitute, approximate, or invent new
83> colors, fonts, radii, or shadows. If a value is missing, ask the
84> user before adding one.
85 
86### 1 · Your role
87 
88You are building UI for a project that has adopted **Hemlock Paper** as its
89design system. Treat `DESIGN.md` as the single source of truth.
90Your job is to translate the user's product requirements into
91components and pages that look like they were designed by the same
92person who authored this file.
93 
94### 2 · Token compliance
95 
96- Pull every color, font family, radius, shadow, and spacing value
97  from the frontmatter at the top of this file.
98- Use semantic roles (e.g. `primary`, `accent`, `muted`) — never
99  hard-code hex values that bypass the system.
100- When a token can be expressed as a CSS variable, declare it once
101  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 recipes
106 
107Use these recipes verbatim when building the corresponding component.
108 
109#### Buttons
110 
111Four variants are defined. Pick one — never blend variants or invent a fifth.
112 
113- **Primary** — sharp shape, bg `#244232`, text `#f3ecd6`, padding `12px 24px`, weight `500`, uppercased.
114- **Secondary** — sharp shape, text `#1c1a14`, border `1px solid #1c1a14`, padding `12px 24px`, weight `500`, uppercased.
115- **Outline** — sharp shape, text `#1c1a14`, border `1px solid rgba(28,26,20,0.18)`, padding `12px 24px`, weight `500`, uppercased.
116- **Ghost** — sharp shape, text `#6b6759`, padding `12px 16px`, weight `500`, uppercased.
117 
118Reach for **primary** as the single dominant CTA per screen.
119**Secondary** for the supporting action. **Outline** for tertiary
120actions in toolbars. **Ghost** for inline links and table actions.
121 
122#### Cards
123 
124- Background: `#f3ecd6`
125- Border: `1px solid rgba(28,26,20,0.12)`
126- Shadow: `none`
127- Radius: `radius.lg` (`4px`)
128- Internal padding: `20px` for compact cards, `24–28px` for content cards.
129 
130#### Tabs
131 
132Variant: `underline`. Flat row of labels. Active tab gets a 2px underline in the accent color — no fill.
133 
134#### Charts
135 
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 pairings
141 
142- **Display (`EB 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 constraints
147 
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 — verify
157 
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

169## 1. Atmosphere
170 
171Hemlock Paper is a warm off-white paper system that earns trust through quiet. The page surface is cream paper `#f3ecd6` — warmer than a clinical white-paper, calmer than parchment. Headlines run in EB Garamond 400 at 104px — the classical serif at scale, never bold. Body sits in Inter at 17px on a 1.72 leading — a generous reading rhythm that signals long-form respect. UI labels run in Inter 500 with 0.14em uppercase tracking — the engraved-foundry voice. The single accent is forest green `#244232` reserved for verified marks (a small filled square in front of a verified item), the primary CTA, and the active step in a process flow.
172 
173The discipline is in the proportion: huge classical serif on warm paper, generous body leading, and one forest-green mark per page that reads as a notary stamp. The system never lifts a card and never adds shadows.
174 
175**Signature moves**
176- EB Garamond 400 at 104px headlines — classical serif at scale, never bold
177- Warm cream paper `#f3ecd6` — never bright white, never beige
178- Forest green `#244232` exclusively on verified marks + primary CTA + active step
179- 17px Inter body on 1.72 leading — generous long-form reading rhythm
180- 0.14em uppercase tracking on UI labels — engraved-foundry voice
181- Sharp 2-4px corners — letterpress precision, no shadows anywhere
182 
183## 2. Palette
184 
185### Surfaces
186- **Cream Paper** `#f3ecd6` — page background (warm off-white)
187- **Cream Lift** `#ebe4cf` — secondary surfaces, footer
188- **Hairline** `rgba(28,26,20,0.12)` — every divider, every card edge
189 
190### Ink
191- **Ink** `#1c1a14` — text, headings (warm near-black)
192- **Ink 50** `#6b6759` — secondary text, mono captions
193 
194### Accent
195- **Forest** `#244232` — verified marks, primary CTA, active step indicator
196- **Forest Soft** `rgba(36,66,50,0.10)` — focus ring, hovered step
197 
198## 3. Typography
199 
200| Role | Font | Size | Weight | Leading | Tracking |
201|------|------|------|--------|---------|----------|
202| Hero | EB Garamond | 104px | 400 | 0.98 | -0.035em |
203| H1 | EB Garamond | 60px | 400 | 1.06 | -0.022em |
204| H2 | EB Garamond | 30px | 500 | 1.22 | -0.012em |
205| Pull Quote | EB Garamond (italic) | 26px | 400 | 1.4 | -0.008em |
206| Body | Inter | 17px | 400 | 1.72 | -0.005em |
207| UI / Button | Inter | 13px | 500 | 1.4 | 0.14em uppercase |
208| Caption / Date | JetBrains Mono | 11px | 500 | 1.0 | 0.10em uppercase |
209| Reference Number | JetBrains Mono | 13px | 500 | 1.0 | 0.04em tabular-nums |
210 
211EB Garamond at 400 only — bold breaks the classical proportion. Italic reserved for pull quotes and the verified-by line.
212 
213## 4. Buttons
214 
215### Primary (Forest — Engage)
216```css
217background: #244232;
218color: #f3ecd6;
219padding: 12px 24px;
220border-radius: 3px;
221text-transform: uppercase;
222letter-spacing: 0.14em;
223font-weight: 500;
224```
225 
226The forest-green on warm paper reads as a wax-stamped notary mark, not a marketing CTA.
227 
228### Secondary (Ink Outline)
229- Transparent, 1px solid ink, ink text — same near-sharp shape, same wide tracking
230 
231### Outline & Ghost
232- Outline: transparent, 1px hairline at 18% ink
233- Ghost: no border, ink-50 uppercase
234 
235## 5. Cards (rare)
236 
237The system prefers hairline-divided sections over cards. When a card is needed, it is sharp 4px corners with a 1px hairline at 12% ink — never lifted, never shadowed. Practice-area cards may add a 1px ink top border (3px wide) — the only chrome.
238 
239## 6. Charts
240 
241Thin precise bars (3px wide, 12px gap). One bar in forest, others in 22% ink. NO gridlines. Y-axis labels in JetBrains Mono uppercase 11px. Charts are reserved for performance breakdowns and read as inscribed exhibits.
242 
243## 7. Tabs
244 
245Underline 1px in ink for the active state. Inactive tabs are ink-50 in Inter 500 uppercase 0.14em. The active label often switches to EB Garamond italic at the same size — that is the rhythm change.
246 
247## 8. Spacing
248 
249- Base 8px
250- Scale: `8, 16, 24, 32, 48, 64, 96, 128, 200`
251- Section padding: 160px desktop, 80px mobile — long-form rhythm
252 
253## 9. Do's & don'ts
254 
255✅ **Do**
256- Use EB Garamond at 400 only — anything heavier breaks the classical proportion
257- Hold the warm cream paper surface — bright white reads as web app, beige reads as old textbook
258- Reserve forest green for verified marks + primary CTA + active step exclusively
259- Use 17px Inter body on 1.72 leading — long-form reading respect
260 
261❌ **Don't**
262- Use stock photography of pillars, trees, or "trust" imagery — the typography earns it
263- Use EB Garamond at 600+ — bold breaks the classical proportion
264- Use a second accent — forest alone, on three specific surfaces
265- Add shadows or lifted cards — hairlines and breathing room carry the layout
266
