Decoded design system

Astro's decoded design system: background #060913, text #ECECEE, accent #59179F, link #61DAFB, primary #1F232E; type scale h1 48px / h2 36px / body 18px; 8px 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	`#060913`
surface	`#131620`
border	`#282B33`
text	`#ECECEE`
text_muted	`#94959A`
primary	`#1F232E`
accent	`#59179F`
link	`#61DAFB`
secondary	`#183341`
button_bg	`#FFFFFF`
button_text	`#F2F6FA`

Using these colors

Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
accent #59179F — accent for emphasis — keep it rare on the page.
primary #1F232E — a brand color — but the call-to-action uses #FFFFFF, not this.
link #61DAFB — inline text links and link-styled controls.
secondary #183341 — 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.
