/*
 * Design system: warm brass-on-neutral light theme, deep slate dark theme. Palette is applied
 * two ways -
 *   1) Bootstrap's own theme variables (--bs-primary, --bs-success, --bs-body-bg, etc.) are
 *      redefined here so every Bootstrap component (buttons, badges, alerts, links, tables)
 *      picks up the new palette automatically, without fighting Bootstrap's !important utility
 *      classes one by one.
 *   2) A smaller set of app-specific tokens (--surface, --ink, --muted, --font-*, ...) drive the
 *      custom shell/card/table styling below.
 *
 * Theme resolution follows the 3-state pattern: bare :root is the light default; the dark media
 * query is guarded with :not([data-theme="light"]) so an explicit light choice always beats the
 * OS preference; [data-theme="dark"] repeats the same values so the toggle wins in both
 * directions. See js/theme.js for the toggle itself.
