/**
 * v1.4.19 A6 — Settings consistency snapshot at Pixel-5 (393 CSS px).
 *
 * Marc reported four interlocking inconsistencies on the mobile
 * settings shell:
 *
 *   1. Input heights differed across sections — `<Input>` rendered at
 *      36 px, the AI active-provider native `<select>` at 40 px, the
 *      AI add-provider select at 32 px, the Dashboard "Compare to"
 *      `<SelectTrigger>` at 44 px. Same shell, four heights.
 *   2. Action buttons inside title rows ("Change password", "Restart
 *      onboarding tour") could overflow the parent card on narrow
 *      viewports because the `flex justify-between` row never wrapped.
 *   3. The Sprache (language) select was buried half-way down the
 *      Profile card, paired with a profile-data field (date of birth).
 *   4. Card-internal `space-y-*` rhythm varied between 3 / 4 / 5 / 6.
 *
 * The fixes:
 *
 *   - `h-9` (36 px) is the canonical input height across Settings.
 *   - Title + action rows use `flex-col` on `<sm` and `flex-row` on
 *     `>=sm` so the action button stacks below on mobile.
 *   - Sprache lifted into its own row at the bottom of the Profile
 *     card, `max-w-xs` on `>=sm` so it doesn't render heavier than
 *     other fields.
 *   - Card-internal spacing standardised on `space-y-4`.
 *
 * This spec captures the post-fix invariants. It is mobile-only — the
 * desktop project skips it.
