/* Mobile Overrides
 *
 * This file holds all top-level `@media (max-width: 768px)` blocks that were
 * historically interleaved through styles.css. After modularization, the
 * desktop rules for migrated components live in module files which load
 * AFTER styles.css. To preserve the original cascade (mobile @media wins
 * over base desktop rule on small screens), these mobile blocks must load
 * LAST in the cascade — hence this file is the final <link> in index.php.
 *
 * Do not put new mobile rules here — co-locate them inside the relevant
 * module's CSS file. This file exists to repair pre-modularization cascade.
