/* CA Fuel NPV Calculator — scoped styles.
   Every selector is prefixed with .fuel-calc so rules cannot leak into
   site chrome. Site tokens (--bg, --card, --ink, --muted, --accent,
   --warm, --rule, --rule-soft) come from base.css and switch with
   [data-theme]. Calculator-specific tokens are defined here with
   explicit dark + light overrides. */

/* Fallback theme tokens — zero specificity via :where() so base.css always
   wins when present (live site + theme toggle unaffected). These only take
   effect when base.css fails to load, e.g. a bare Quarto/_site preview that
   isn't served from the assembled dist/ root. Values mirror base.css dark. */
