- Scale floor perspective with viewport height so grid reaches horizon
on full-screen KDE (was broken with fixed 700px perspective value)
- Increase grid line thickness 1px → 2px to reduce sub-pixel flickering
- Remove DANCEBOT-9000 title text
- Add viewport meta tag for correct layout in WebEngineView
- Add dev-server.sh (port 3000) with in-browser music ticker shim
