Decoded design system

Heptabase's decoded design system: background #F7F7F7, text #000000, accent #FF5F57, link #6A6972, primary #FF5F57; type scale h1 48px / h2 36px / body 17px; 4px spacing base; 6px base radius. The single interactive/action color is #2E2E2E — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #2E2E2E — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #FF5F57 — one role, not several (the action color).
• accent #FF5F57 — accent for emphasis — keep it rare on the page.
• link #6A6972 — reads as a neutral UI color, not a link accent — verify against the reference (action = #2E2E2E).
• secondary #207DFF — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Heptabase — Design System

> light, modern, medium, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#F7F7F7` |
| surface | `#E8E8E8` |
| border | `#D1D1D1` |
| text | `#000000` |
| text_muted | `#5D5D5D` |
| primary | `#FF5F57` |
| accent | `#FF5F57` |
| link | `#6A6972` |
| secondary | `#207DFF` |
| button_bg | `#2E2E2E` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#2E2E2E` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent` are all `#FF5F57` — one role, not several.
- **accent** `#FF5F57` — accent for emphasis — keep it rare on the page.
- **link** `#6A6972` — reads as a neutral UI color, not a link accent — verify against the reference (action = #2E2E2E).
- **secondary** `#207DFF` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FDFCFB` 82.7% · `#C8C2AF` 8.1% · `#81837A` 5.6% · `#DEEADE` 3.6%

## Typography

- Heading: **Inter**
- Body: **Inter**
- Mono: **ui-monospace** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 48px / 500 · lh 62px · tracking -1.58px |
| h2 | 36px / 500 · lh 47px · tracking -0.54px |
| body | 17px / 400 · lh 26px |
| small | 16px / 400 · lh 20px |

- Weight ladder: 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Inter — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 3px, 4px, 5px, 6px, 8px, 10px, 12px, 16px, 20px — snap all gaps/padding to these
- section rhythm: 40px top/bottom padding per section (measured)

## Radius
- base: 6px
- button: 9999px
- card: 6px
- pill: 9999px
- sharp: 3px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#2E2E2E` / `#FFFFFF` | none | 9999px | 8px 16px 8px 16px | 500 16px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#2E2E2E` | none | 8px | 8px 12px 8px 12px | 400 16px | none |

**States (measured, not guessed)**

- transition: `all 0.2s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 5.501px 17.289px 0px, rgba(0, 0, 0, 0.15) 0px 3.143px 3.143px 0px, rgba(0, 0, 0, 0.1) 0px 0px 1.179px 0px`

## Motion
- durations: 200ms (dominant) · 150ms · 500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease-out`
- animated properties: color, background-color, border-color, text-decoration-color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Their own tokens (verbatim from :root)

| Token | Value |

_…and 108 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1300px · common grid: 3-col
- nav: 72px sticky · bg #FDFCFB

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 184 | 1281 | 3 | — | 0/0 | 28/28/44 |
| 2672 | 949 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.hero-segment-content` @0ms → `span.ml-0.5` @1ms → `div.pointer-events-none` @322ms → `div.absolute` @322ms
- `div.hero-segment-content` — opacity 0→1 · transform translateY(4px)→translateY(0px) — 220ms ease-out
- `span.ml-0.5` — opacity 1→0 — 1200ms steps(1) · loops
- scroll reveal: 3 elements rest at opacity 0, animate in over 0.5s cubic-bezier(0.4, 0, 0.2, 1) (0 revealed during the drive).

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #FFFFFF · no underline

## Responsive (measured)
- breakpoints: 600px · 640px · 768px · 800px · 840px · 916px
- mobile (390px): hero 18px · body 16px · nav: hamburger

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
