Wake lock (Prevent Sleep) toggles now persist across reloads via
localStorage in both AdminView and DisplayView. Buttons repositioned
inline in AdminView campaigns header bar (was floating overlay causing
overlap on tablets). DisplayView buttons persist localStorage too.
Wake lock acquire failure now shows toast with fix hint (HTTPS or
Chrome flag). Fullscreenchange listener re-acquires wake lock (Android
discards on screen off).
dev-start.sh: auto-detects LAN IP (en0/en1), frontend binds 0.0.0.0,
backend URL inlined as LAN IP so phones reach backend. DANGEROUSLY_DISABLE_HOST_CHECK
for LAN access. Outputs LAN URL + wake lock flag instructions.
Docs: README 'Prevent Sleep (Wake Lock)' section covering secure context
requirement, Android Chrome flag workaround for LAN testing, iOS Safari
standalone PWA bug. DEVELOPMENT.md LAN access + wake lock note.
