Decoded design system

Knock's decoded design system: background #FFFFFF, text #000000, accent #FF6C52, link #222222, primary #FF6C52; type scale h1 56px / h2 48px / body 24px; 4px spacing base; 6px base radius. The single interactive/action color is #FF6C52 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Knock — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#FF6C52` |
| accent | `#FF6C52` |
| link | `#222222` |
| secondary | `#F45B58` |
| button_bg | `#FF6C52` |
| button_text | `#FAFAFA` |

**Using these colors**

- **Action color** `#FF6C52` — 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`, `button_bg` are all `#FF6C52` — one role, not several (your action color).
- **accent** `#FF6C52` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **link** `#222222` — reads as a neutral UI color, not a link accent — verify against the reference (action = #FF6C52).
- **secondary** `#F45B58` — 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): `#FFFFFF` 94.6% · `#A59795` 5.4%

## Typography

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

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 56px / 500 · lh 62px |
| h2 | 48px / 500 · lh 56px · tracking 0.1px |
| h3 | 30px / 500 · lh 36px · tracking -0.23px |
| body | 24px / 500 · lh 32px · tracking -0.16px |
| small | 20px / 400 · lh 28px |
| eyebrow | 15px / 600 · tracking 0.42px |

- Weight ladder: 400 · 500 · 600 — 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: 4px, 6px, 8px, 10px, 12px, 16px, 20px, 24px, 38px, 40px — snap all gaps/padding to these
- section rhythm: 128px top/bottom padding per section (measured)

## Radius
- base: 6px
- button: 4px
- card: 4px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FF6C52` / `#FAFAFA` | none | 4px | 8px 12px 8px 12px | 600 16px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#000000` | none | 7px | 0px 0px 0px 0px | 400 16px | none |

**States (measured, not guessed)**

- primary hover: background `#E33A1E`
- primary focus: outline `1px auto rgb(255, 86, 54)`
- transition: `color 0.2s cubic-bezier(0.4, 0, 1, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(28, 32, 36, 0.08) 0px 14px 30px 0px, rgba(28, 32, 36, 0.08) 0px 1px 3px 0px`

## Motion
- durations: 200ms (dominant) · 150ms · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0.4, 0, 1, 1)`
- animated properties: border-color, color, background-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)

_…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 1440px · common grid: 6-col
- nav: 65px sticky · backdrop blur(5px) · border-bottom 1px solid rgb(200, 206, 213) · bg rgba(255, 255, 255, 0.95)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 55 | 434 | — | — | 0/0 | — |
| 489 | 865 | — | — | 80/0 | — |
| 569 | 785 | 12 | 4 | 0/0 | — |
| 1354 | 312 | 6 | 32 | 0/0 | — |

## Motion choreography (measured)
Load order: `span.absolute` @0ms → `span.ml-px` @390ms → `canvas.w-full`×21 @667ms → `div.fixed` @2393ms → `svg.lucide` @4727ms
- `span.absolute` — opacity 0.75→0 · transform none→scale(2) — 1000ms cubic-bezier(0, 0, 0.2, 1) · loops
- `svg.lucide` — transform none→rotate(360deg) — 1000ms · loops
- stagger: `div` ×12 — 30ms apart
- scroll reveal: 19 elements rest at opacity 0, translateY(20px), animate in over 500ms (13 revealed during the drive).

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

## Components (measured)
- link: #222222 · no underline — hover #F45B58

## Responsive (measured)
- breakpoints: 512px · 650px · 768px · 1024px · 1100px · 1200px
- mobile (390px): hero 34px · body 16px · nav: inline

## 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.
