/* ui-polish.css — program-wide visual unification.

 * Loaded last in head_part.html so it refines the base theme + design tokens.
 *
 * Two goals:
 *   1. One unified "card" treatment shared by `.section-card` (the detail-tab
 *      data cards) and the `.ddform-fieldset` form cards, so every declaration
 *      tab reads as the same family of cards instead of bare tables.
 *   2. A gentle, consistent button refinement across the whole program
 *      (radius, weight, resting shadow, hover lift, crisp focus ring).
