/* ══════════════════════════════════════════════════════════════════════════
   Theme picker (2026-10-10)

   Three round swatches in one row, the theme name underneath. This block is
   the single owner of the picker's look; the older rules in rewards-themes,
   settings-glass, desktop-settings, learning-settings and steppe-light drew a
   bordered card per theme and are overridden here, not edited.

   Scope: only `.tp-theme-picker` and what is inside it, plus the vertical
   alignment of its own row. Nothing else on Settings is touched.

   Contract with JS (ui/modals.js `setTheme`, main.js `initThemeControls`):
   `[data-theme-choice]`, `.is-selected`, `aria-checked`, role radio/radiogroup.

   Each swatch is drawn from three colours of the theme it stands for, never
   from the active theme, so the picker reads the same wherever it is shown:
     --tp-swatch-lit / --tp-swatch-deep   surface, lit from the upper left
     --tp-swatch-accent(-lit)             the accent segment
     --tp-swatch-edge                     hairline that keeps the disc defined
   Archived themes keep ready-made values in _archive/themes-archived.css.

   `!important` appears only where an older `!important` forces it:
   steppe-light.css paints `.tp-theme-choice` backgrounds, and
   product-ui-cleanup.css sets every `strong` inside a settings row.
