/* Tempo's look and feel, layered on Bootstrap 5.
 *
 * Tokens first (light, then dark), then Bootstrap overrides, then Tempo components.
 * Coral is the brand color. Text on coral uses --tempo-accent (a darker coral in
 * light mode, a lighter one in dark mode) so it keeps 4.5:1 contrast.
 * Chart palettes are validated for color blindness in both modes (see the
 * dataviz notes in docs/architecture.md). */
