 Dark/light modes via `data-theme`; fresh installs default to System mode so the resolved theme follows `prefers-color-scheme` until the user explicitly chooses Light, Dark, or System. 76 color themes via `data-color-theme` (lazy-loaded from `app/public/theme-data.css`), including the Shadcn zinc-neutral theme with an orange default highlight/accent, Shadcn Custom (the same base with sanitized per-token color-picker overrides), and its color family: Shadcn Blue/Green/Red/Purple/Pink/Orange/Yellow, Shadcn Mono Red/Blue/Green/Purple/Pink/Orange/Yellow (grayscale surfaces with color-specific accents; legacy `shadcn-mono` selections migrate to Shadcn Mono Red), Shadcn Black (pure black and white), Shadcn Gray (fully neutral zinc-gray accent), and Shadcn Gray Blue (blue-gray slate neutral surfaces with a muted slate-blue accent). Air is the minimal, borderless, paper-like preset with near-monochrome tokens and CSS-only chrome flattening. Glass Silver preserves the Glass theme's frosted translucent surfaces and transparent modal overlay behavior while using silver and graphite accents instead of purple/pink.
