/* Re-theme Pico so every default-styled element (buttons, inputs, cards,
   tables) picks up the new look with no changes needed in most templates.
   Pico defines these on `:root:not([data-theme=dark])`, which out-specifies
   a plain `:root` rule regardless of source order — !important is the
   reliable way to win against a selector we can't out-specify cleanly. */
