Decoded design system

Plane's decoded design system: background #FFFFFF, text #000000, accent #000000, link #000000, primary #000000; type scale h1 16px / h2 16px / body 16px; 4px spacing base; 8px base radius. The single interactive/action color is #111111 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

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.
