 *   outer gutters (12px each side).
 *
 * Rule 2 — Compact vertical rhythm
 *   Section top padding on mobile: ≤ 16px.
 *   Card internal padding on mobile: 12–16px.
 *   Avoid 32px+ vertical padding on full-height page sections.
 *
 * Rule 3 — Tab bars
 *   On mobile, tab selectors must be horizontal scrollable pill rows,
 *   not vertical stacks. Use overflow-x: auto + flex-wrap: nowrap.
 *   Tab pills: padding 6px 14px, border-radius: var(--radius-full).
