/* ==================== SHARED THEME TOKENS ====================
   Color/spacing custom properties for index.html and admin.html.
   Both pages set data-theme (dark/light/navy) via js/theme.js's setTheme().
   Page-specific component overrides (e.g. navy-theme fixes for a page's own
   classes) stay in that page's own <style> block — only the token
   definitions themselves live here, so a palette change is made once. */

/* ===== THEME: NAVY CREAM GOLD =====
   NOTE: --bg-surface, --text-primary and --accent-blue are all the same
   dark navy on purpose (this theme's "dark accent" surfaces use navy text
   elsewhere), but that means any plain/unstyled text placed directly on a
   --bg-surface background is invisible. Any page adding a new component
   that uses --bg-surface as a background MUST give its own text an explicit
   light color for [data-theme="navy"] — see index.html's ".top-nav"/".tab-bar"
   overrides and admin.html's ".topbar"/".table-wrap tbody" overrides below
   this file for the established pattern. */
