Cap — Design System

light · modern · medium · tailwind · confidence 92% · deep decode

Cap positions itself as the open-source Loom with gallery restraint: PP Neue Montreal at 60px/500 in black on soft grey #F2F2F2, 16px body, and quiet 6px-radius white buttons. Recorder UI and share-page frames float in generous whitespace — screen recording presented like a design-studio tool, its open-source badge worn as understatement.

Tokens

Cap's decoded design system: background #F2F2F2, text #000000, accent #3B82F6, link #3B82F6, primary #2563EB; type scale h1 60px / h2 36px / body 13px; 4px spacing base; 8px base radius. The single interactive/action color is #2563EB — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Cap — Design System

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

Cap positions itself as the open-source Loom with gallery restraint: PP Neue Montreal at 60px/500 in black on soft grey #F2F2F2, 16px body, and quiet 6px-radius white buttons. Recorder UI and share-page frames float in generous whitespace — screen recording presented like a design-studio tool, its open-source badge worn as understatement.

## Colors

| Role | Value |
|------|-------|
| bg | `#F2F2F2` |
| surface | `#E3E3E3` |
| border | `#CDCDCD` |
| text | `#000000` |
| text_muted | `#5B5B5B` |
| primary | `#2563EB` |
| accent | `#3B82F6` |
| link | `#3B82F6` |
| secondary | `#8B5CF6` |
| button_bg | `#2563EB` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#2563EB` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `button_bg` are all `#2563EB` — one role, not several (your action color).
- `accent`, `link` are all `#3B82F6` — one role, not several.
- **accent** `#3B82F6` — accent for emphasis — keep it rare on the page.
- **secondary** `#8B5CF6` — 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): `#F2F2F2` 75.4% · `#404041` 11% · `#6A80A7` 6.9% · `#D6D8DB` 6.6%

## Typography

- Mono: **ui-monospace** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 36px / 500 · lh 40px |
| body | 18px / 400 · lh 28px |
| small | 16px / 500 · lh 24px |
| eyebrow | 14px / 500 · tracking 0.7px |

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 10px, 12px, 14px, 16px, 20px, 24px — snap all gaps/padding to these

## Radius
- base: 8px
- button: 9999px
- card: 12px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#2563EB` / `#FFFFFF` | 1px solid rgb(30, 64, 175) | 9999px | 0px 20px 0px 20px | 500 16px | rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(255, 255, 255, 0.2) 0px 1.5px 0px 0px inset |
| secondary | `#FFFFFF` / `#838383` | none | 6px | 0px 8px 0px 8px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `#1D4ED8`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `#F3F4F6` · color `#0090FF`
- transition: `color 0.2s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 20px 25px -5px, rgba(0, 0, 0, 0.05) 0px 8px 10px -6px`
- card: `rgba(0, 0, 0, 0.05) 0px 4px 10px 0px`
- button: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(255, 255, 255, 0.2) 0px 1.5px 0px 0px inset`
- overlay: `rgba(0, 0, 0, 0.28) 0px 25px 50px -12px, rgba(0, 0, 0, 0.16) 0px 12px 24px -8px`

## Motion
- durations: 150ms (dominant) · 200ms · 600ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- 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.

_…and 93 more measured on the page._

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

## Layout (measured)
- container max 960px · common grid: 2-col
- nav: 58px fixed

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 140 | 762 | 2 | — | 0/0 | 35/65 |

## Motion choreography (measured)
Load order: `div.flex` @0ms → `div.absolute` @0ms → `div.absolute` @0ms → `div.absolute`×2 @1046ms → `div.absolute`×2 @1046ms → `button.flex-1`×2 @3246ms
- `div.flex` — transform translate(0px)→translate(-50%) — 30000ms · loops
- stagger: `span` ×20 — 28ms apart
- stagger: `div` ×6 — 70ms apart
- scroll reveal: 17 elements rest at opacity 0, translateY(20px), animate in over 0.15s cubic-bezier(0.4, 0, 0.2, 1) (17 revealed during the drive).

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

## Components (measured)
- link: #838383 · no underline — hover #0090FF

## Responsive (measured)
- breakpoints: 480px · 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 36px · 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.
