- Link the theme after mobile.css on mobile builds (OASIS_MOBILE=1) so
it wins by cascade; removed ~420 !important, keeping only the few that
override epsylon's inline styles.
- Reveal the quick bar without !important: the inline display:none is
emitted only on desktop.
- Remove unused oasis-mobile-nav.js (it was never linked and would be
blocked by CSP script-src 'none' on clearnet).
- epsylon's mobile.css and OasisMobile.css left untouched.
Rebase onto upstream 0.9.0. Mobile topbar (logo->home, avatar->profile),
hexagon category nav (hive) and bottom bar; remove the six top-bar
buttons (inbox/pm/publish/search/graphos/peers) that cluttered the header.
Theme OasisMobileUX carries topbar/hexagon/bottombar styles.
- Selectable Oasis-Mobile-UX theme; mobile.css kept intact
- Hexagon category launcher on home (10 categories with expandable modules)
- Customizable bottom bar (up to 4 shortcuts, Peers/Invites fixed)
- Empty states and collapsible activity filters
