Dark Mode System

Token approach

:root {
  --bg: #f6f7f9;
  --surface: #ffffff;
  --text: #12141a;
  --muted: #5c6370;
  --accent: #3b82f6;
  --danger: #dc2626;
  --border: rgba(0,0,0,.08);
}
[data-theme="dark"] {
  --bg: #0e1014;
  --surface: #171a21;
  --text: #eef1f6;
  --muted: #9aa3b2;
  --accent: #60a5fa;
  --danger: #f87171;
  --border: rgba(255,255,255,.10);
}

Rules

Theme via tokens, not scattered hex
Follow prefers-color-scheme when mode = system
Persist user choice in settings
Test contrast for text, borders, focus rings
Images/icons may need theme variants

Pitfalls

Pure #000 backgrounds with gray text (muddy)
Box-shadows that disappear on dark
Hardcoded white modals in dark app

Acceptance

Toggle switches all chrome in one frame
Focus ring visible in both themes
