Tokens

Bilt's decoded design system: background #010A13, text #CCCED0, accent #97C6EA, link #010A13, primary #97C6EA; type scale h1 24px / h2 32px / body 11.2px; 4px spacing base; 0px base radius. The single interactive/action color is #97C6EA — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#010A13`
surface	`#0D151E`
border	`#1F272F`
text	`#CCCED0`
text_muted	`#7E8388`
primary	`#97C6EA`
accent	`#97C6EA`
link	`#010A13`
secondary	`#CCCED0`
button_bg	`#97C6EA`
button_text	`#0000EE`

Using these colors

Action color #97C6EA — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, button_bg are all #97C6EA — one role, not several (the action color).
accent #97C6EA — 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 #010A13 — 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 #CCCED0 — 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.

**Using these colors**

- **Action color** `#97C6EA` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `button_bg` are all `#97C6EA` — one role, not several (your action color).
- **accent** `#97C6EA` — 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** `#010A13` — 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** `#CCCED0` — 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.

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.

Export: Tailwind v4 (@theme)
