- Replace SB Admin 2 sidebar with a clean fixed sidebar (desktop)
and a sticky bottom tab navigation (mobile, ≤767px)
- Sidebar collapses to icon-only mode with state persisted in localStorage
- Logo is a functional home link on all viewports
- Mobile: full-width content, bottom nav replaces sidebar
- Dashboard: 6 OBD stat cards (status, speed, RPM, coolant, throttle, fuel)
wired to live socket events; removed all placeholder buttons/dropdowns
- GPS info section cleaned up (lat/lon display instead of X/Y paragraphs)
- DTC page: live /api/dtc wiring — MIL indicator + DTC table populated from API
- New /api/dtc route added to app.py (mil + codes)
- yaris.js: added obd_coolant_temp / obd_fuel_level / obd_throttle listeners
- yaris.css: full rewrite — layout variables, sidebar, bottom nav, OBD cards,
border-start utilities, mobile padding for bottom nav
