   Design tokens

   Hues are stored as bare RGB CHANNELS, not colours, so a tint can be written
   `rgb(var(--primary-rgb) / 0.08)` and still follow the theme. Forty-odd
   hardcoded `rgba(99, 102, 241, …)` literals used to be scattered through this
   file, which is why light mode was impossible without touching all of them.

   Everything below the channel block is semantic: rules should ask for
   --bg-surface or --text-muted, never for a raw colour. [data-theme="light"]
   then only has to restate the semantic layer.
