// Package theme resolves the named colour scheme the TUI renders with. A theme
// is a flat set of semantic tokens — roles like "muted" or "firing", never hues
// — so a new scheme is a table of colours rather than a change to the views.

// Theme is the palette the UI draws from. Every token is a foreground except
// OnPrimary, which is the text colour for the two places that invert: the
// active tab and the selected table row.
//
// Colours are truecolor hex; lipgloss downsamples them for 256- and 16-colour
// terminals and drops them entirely under NO_COLOR, so themes do not carry
// fallbacks of their own.
