Decoded design system

Highlight's decoded design system: background #0D0225, text #ECECEE, accent #72E4FC, link #0D0225, primary #72E4FC; type scale h1 16px / h2 58px / body 22px; 8px spacing base; 8px base radius. The single interactive/action color is #72E4FC — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#0D0225`
surface	`#1A1031`
border	`#2E2543`
text	`#ECECEE`
text_muted	`#9793A1`
primary	`#72E4FC`
accent	`#72E4FC`
link	`#0D0225`
secondary	`#6C37F4`
button_bg	`#72E4FC`
button_text	`#000000`

Using these colors

Action color #72E4FC — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #72E4FC — one role, not several (the action color).
accent #72E4FC — 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 #0D0225 — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
secondary #6C37F4 — 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.
