/* Daily Byte — shadcn/ui design system, hand-ported to plain CSS.
 *
 * The site has no build step, so instead of Tailwind + the shadcn CLI this file
 * implements the same thing by hand: shadcn's semantic token block (identical
 * variable names, so a theme copied from ui.shadcn.com maps one-to-one) plus the
 * component recipes the pages actually use — button, badge, card, accordion,
 * separator.
 *
 * The palette is the "Orange" spec from the app's own theme gallery
 * (mobile/src/theme/themes.ts): Tailwind's stone ramp as the neutral, orange as
 * the single saturated color. Dark is the default, matching the app; the toggle
 * in the nav flips :root[data-theme].
