- perf-tray.py drops its duplicated Thermals/detect_mode/_read*/MODES/SCRIPT
  and imports them from tools/bridge/perf.py — the tray is now just the Qt face
  of the same logic the web Bridge serves (one source of truth)
- tray icon restyled with the ParVagues signature wave (drawn in Qt, no asset)
  under the heat-coloured temp badge
- parvagues-bridge.service → WantedBy=default.target so it boots headless with
  linger (always-on dashboard, no login needed); tray stays graphical-session
- deployed: bridge enabled+active on :8773, tray restarted, linger enabled
