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 **Linear Orbit** 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 `#5e6ad2`, text `#ffffff`, padding `7px 14px`, weight `500`, shadow `rgba(94,106,210,0.18) 0 1px 0 inset, rgba(0,0,0,0.04) 0 1px 1px`.
111- **Secondary** — rounded shape, bg `#ffffff`, text `#0e1116`, border `1px solid rgba(14,17,22,0.08)`, padding `7px 14px`, weight `500`.
112- **Outline** — rounded shape, text `#0e1116`, border `1px solid rgba(14,17,22,0.10)`, padding `7px 14px`, weight `500`.
113- **Ghost** — rounded shape, text `#5a6273`, padding `7px 12px`, 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: `#ffffff`
122- Border: `1px solid rgba(14,17,22,0.06)`
123- Shadow: `rgba(14,17,22,0.06) 0 0 0 1px, rgba(14,17,22,0.03) 0 1px 2px`
124- Radius: `radius.lg` (`10px`)
125- Internal padding: `20px` for compact cards, `24–28px` for content cards.
126
127#### Tabs
128
129Variant: `underline`. Flat row of labels. Active tab gets a 2px underline in the accent color — no fill.
130
131#### Charts
132
133- Bar/line variant: `thin-bars`
134- Highlight strategy: `single` — emphasize a single bar/point per chart.
135
136#### Typography pairings
137
138- **Display (`Inter Display`)** — h1, h2, hero headlines, brand wordmarks.
139- **Body (`Inter`)** — paragraphs, labels, button text, form inputs.
140- **Mono (`JetBrains Mono`)** — code, eyebrows, metadata, numerals in tables.
141
142### 4 · Hard constraints
143
144Never do any of the following without explicit instruction from the user:
145
146- Introduce a new color, font, radius, or shadow that isn't declared above.
147- Mix this system with another (e.g. don't paste in Material or Bootstrap defaults).
148- Use generic gradient defaults (purple→blue, peach→pink) — they break the system's voice.
149- Reach for emoji icons. 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 — verify
153
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

165## 1. Atmosphere
166
167Linear Orbit is the workspace UI distilled. The page is a cool off-white that reads as paper under daylight, never warm, never blue-tinted. Type runs at Inter with -0.045em tracking at hero scale — compressed, engineered, technical without being cold. The single accent is an indigo `#5e6ad2` reserved for the primary CTA, the active tab underline, and the focused chart series. Every other interactive surface lives in pure greyscale.
168
169The signature move is restraint at the divider level: 1px hairlines at `rgba(14,17,22,0.06)` carry the entire structure. No card shadows, no fills, no chrome — the grid is the chrome.
170
171**Signature moves**
172- Inter Display at hero with -0.045em tracking — text feels engineered, not decorative
173- 6% ink hairlines as the only divider — never a solid grey, never a fill
174- Indigo `#5e6ad2` as the *only* color in the entire system
175- Buttons sit on a 1px inset highlight, never a drop shadow
176- Underline tabs with the indigo accent, never pills, never boxed
177- Mono used exclusively for status labels and inline metrics
178
179## 2. Palette
180
181### Core
182- **Ink** `#0e1116` — text, headings, dark surface
183- **Surface** `#ffffff` — cards, modals
184- **Page** `#f5f6f8` — cool off-white background
185- **Hairline** `rgba(14,17,22,0.06)` — every divider, every card edge
186
187### Accent
188- **Indigo** `#5e6ad2` — primary CTA, active tab, highlighted chart
189- **Indigo Soft** `rgba(94,106,210,0.10)` — focus ring, hovered tab background
190
191### Neutrals
192- 700 `#3a4150` · 500 `#5a6273` · 400 `#7a818f` · 200 `#e6e8ec`
193
194## 3. Typography
195
196| Role | Font | Size | Weight | Leading | Tracking |
197|------|------|------|--------|---------|----------|
198| Hero | Inter Display | 52px | 600 | 1.04 | -0.045em |
199| H1 | Inter Display | 36px | 600 | 1.12 | -0.035em |
200| H2 | Inter | 24px | 600 | 1.25 | -0.025em |
201| Body | Inter | 15px | 400 | 1.55 | -0.005em |
202| UI | Inter | 13px | 500 | 1.4 | 0 |
203| Mono / Status | JetBrains Mono | 12px | 500 | 1.0 | 0.04em uppercase |
204
205Three weights only: 400 / 500 / 600. Negative tracking is mandatory above 20px.
206
207## 4. Buttons
208
209### Primary (Indigo)
210```css
211background: #5e6ad2;
212color: #ffffff;
213padding: 7px 14px;
214border-radius: 6px;
215box-shadow: rgba(94,106,210,0.18) 0 1px 0 inset, rgba(0,0,0,0.04) 0 1px 1px;
216```
217
218### Secondary (Hairline)
219- White surface, 1px hairline at 8% ink, ink-700 text
220- Same padding as primary — the bar height never breaks
221
222### Ghost
223- Transparent, 500-weight, no border. Hover: 4% ink wash.
224
225## 5. Cards
226
227- Background `#ffffff`
228- 1px hairline at 6% ink, NO drop shadow
229- Radius 8px (10px for featured)
230- Internal padding 20px / 28px
231- Hover: hairline darkens to 10% ink — that is the only state change
232
233## 6. Charts
234
235Thin precise bars at 6px width with 10px gap. Single bar highlighted in indigo, others in 8% ink. Line charts at 1.25px stroke, 5% fill, dot marker at the live value. Dashed gridlines at 4% ink. Reads like an engineering dashboard, not marketing.
236
237## 7. Tabs
238
239Underline only. Active tab carries a 1.5px indigo bar at the bottom edge; inactive tabs are 500-weight ink-500. No pill tabs, no boxed tabs, ever.
240
241## 8. Spacing
242
243- Base 4px
244- Scale: `4, 8, 12, 16, 20, 24, 32, 48, 64`
245- Section padding: 64px desktop, 32px mobile
246
247## 9. Do's & don'ts
248
249✅ **Do**
250- Use the indigo accent exactly once per screen — primary CTA OR active tab, not both
251- Hold every divider to 6% ink — the discipline IS the design
252- Use JetBrains Mono only for metrics, status, and inline code
253- Keep type tracking negative at every size above 20px
254
255❌ **Don't**
256- Add a second accent color — indigo is alone, by design
257- Use drop shadows on cards — hairlines only
258- Use pill buttons — every button is 6px radius
259- Mix Inter weights beyond 400/500/600
