/* Terminal list UI — light & dark themes (responsive, accessible)
 *
 * Goal:
 * - Compact, keyboard-friendly list of pens.
 * - Meta block (thumbnail + category) and details block (title + description).
 * - Stack meta above details on small screens.
 *
 * Notes:
 * - Uses CSS custom properties for theming.
 * - Grid layout avoids HTML reordering.
 * - Auto-detects system theme; manual override via [data-theme].
