/* Mobile-specific tweaks.
 *
 * Two parallel triggers, same effect:
 *  1. `.page.mobile` — used by the jobclaw_redesign/ JSX design canvas to
 *     preview a phone-sized layout next to the desktop one in a single page.
 *  2. `@media (max-width: 768px)` — fires on actual mobile viewports in
 *     production. Without this, the desktop 1200px grid stays active on
 *     phones and the layout overflows horizontally.
 *
 * Keep the two blocks in lock-step — every rule that lives in one should
 * have a twin in the other. */
