/* ==========================================================================
   CharlestonHacks Innovation Engine — overlays.css (FULL REWRITE)
   Purpose:
   - Provide a consistent modal/overlay system used by Network Filters, BBS, etc.
   - Fix "hidden" not working (causing overlays to appear by default)
   - Improve mobile UX: bottom-sheet modals, scrollable bodies, safe-area padding
