Decoded design system

Superlist's decoded design system: background #181824, text #000000, accent #4F6BED, link #8E8DA0, primary #0000EE; type scale h1 88px / h2 70px / body 18px; 10px spacing base; 0px base radius. The single interactive/action color is #FFFFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
• accent #4F6BED — accent for emphasis — keep it rare on the page.
• primary #0000EE — a brand color — but the call-to-action uses #FFFFFF, not this.
• link #8E8DA0 — reads as a neutral UI color, not a link accent — verify against the reference (action = #FFFFFF).
• secondary #26253B — 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.

## 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.
