Decoded design system

Eraser's decoded design system: background #0B0B0B, text #ECECEE, accent #FFFFFF, link #3898EC, primary #2866DF; type scale h1 90px / h2 26px / body 16px; 4px spacing base; 8px 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

Role	Value
bg	`#0B0B0B`
surface	`#181818`
border	`#2C2C2D`
text	`#ECECEE`
text_muted	`#969697`
primary	`#2866DF`
accent	`#FFFFFF`
link	`#3898EC`
secondary	`#00A9E5`
button_bg	`#FFFFFF`
button_text	`#171717`

Using these colors

Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
accent, button_bg are all #FFFFFF — one role, not several (the action color).
accent #FFFFFF — 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.
primary #2866DF — a brand color — but the call-to-action uses #FFFFFF, not this.
link #3898EC — inline text links and link-styled controls.
secondary #00A9E5 — 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.
