# Dub Style — Quick Rules (source: dub.co, extracted by taste-skill)

## Tokens
- canvasBg: #FAFAFA — Primary Dub page canvas
- surfaceElevated: #FFFFFF — Primary elevated card & bento surface
- surfaceSecondary: #262626 — Secondary interactive container / hover fill
- borderPrimary: #E5E5E5 — Primary structural divider (1px solid #E5E5E5)
- borderSecondary: #D4D4D4 — Secondary nested module or pill border
- textPrimary: #171717 — Hero H1, section H2 & high-contrast foreground
- textMuted: #737373 — Lead paragraphs, descriptions & muted labels
- accentPrimary: #000000 — Primary interactive CTA & brand highlight (8px)
- accentSecondary: #F5F5F5 — Secondary badge, syntax or telemetry highlight

## Typography
- Heading font: Satoshi; body: Inter / Satoshi; mono: GeistMono
- Hero H1: 48px | line-height 55.2px (leading-[1.15]) | letter-spacing 0px (tracking-[0em]) | weight 500 (font-[500]) | color #171717 (text-[#171717]) | font satoshi
- Section H2 (Primary): 48px | line-height 48px (leading-[1]) | letter-spacing 0px (tracking-[0em]) | weight 500 (font-[500]) | color #171717 (text-[#171717]) | font satoshi
- Card / Feature H3: 16px | line-height 24px (leading-[1.5]) | letter-spacing 0px (tracking-[0em]) | weight 500 (font-[500]) | color #0A0A0A (text-[#0A0A0A]) | font Inter
- Body Copy (Paragraph): 20px | line-height 28px (leading-[1.4]) | letter-spacing 0px (tracking-[0em]) | weight 400 (font-[400]) | color #525252 (text-[#525252]) | font Inter

## Components
- Primary button: height 32px, padding 0px 16px, radius 8px, bg #000000, text #FFFFFF, 14px / 400
- Card: bg transparent, border 1px solid #E5E5E5, radius 20px 20px 0px 0px, padding 12px 12px

## Never
- NEVER substitute generic uncalibrated gray backgrounds for Dub’s exact #FAFAFA canvas and #FFFFFF surface pairing.
- NEVER replace Satoshi display typography or ignore its signature scale (48px / 1.15 (w500)).
- NEVER use thick opaque borders that clash with #E5E5E5 (1px solid #E5E5E5).
- NEVER deviate from the signature button geometry (8px) or introduce off-brand saturated gradients.
- NEVER use default browser monospace when rendering code or telemetry—always pair with GeistMono.
