Decoded design system

Subframe's decoded design system: background #FCFCFC, text #232323, accent #9CA3AF, link #171717, primary #FF0000; type scale h1 96px / h2 64px / body 24px; 8px spacing base; 6px base radius. The single interactive/action color is #242424 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FCFCFC`
surface	`#EEEEEE`
border	`#DBDBDB`
text	`#232323`
text_muted	`#757575`
primary	`#FF0000`
accent	`#9CA3AF`
link	`#171717`
secondary	`#8FC4F1`
button_bg	`#242424`
button_text	`#232323`

Using these colors

Action color #242424 — the single interactive color; only on things you click or must notice, never large fills.
accent #9CA3AF — accent for emphasis — keep it rare on the page.
primary #FF0000 — a brand color — but the call-to-action uses #242424, not this.
link #171717 — reads as a neutral UI color, not a link accent — verify against the reference (action = #242424).
secondary #8FC4F1 — 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.

**States (measured, not guessed)**

- primary hover: background `#363636`
- transition: `transform 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)

## Motion
- durations: 150ms (dominant)
- easings: `linear` (dominant) · `cubic-bezier(0.4, 0, 0.2, 1)`
- animated properties: transform

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

_…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 1020px · common grid: 2-col
- nav: 0px

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 1134 | 1403 | 6 | 4 | 192/48 | 5/20/20/20/20/16 |

## Motion choreography (measured)
Load order: `a.carousel-dot`×2 @0ms → `div.design-card`×2 @0ms → `div.flex` @118ms → `div.absolute` @118ms
- stagger: `div` ×4 — 80ms apart
- scroll reveal: 12 elements rest at opacity 0, animate in over 700ms (8 revealed during the drive).

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

## Responsive (measured)
- breakpoints: 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 56px · body 12px · 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.
