Battery chart: stats line spans the full width so the CPU MHz figure no longer
wraps; the CPU series + chip now use the RF-monitor noise-floor grey (0x4A5256).
Telemetry: the window no longer auto-requests on open — it shows history and a
Request button (async refresh glyph, left of the gear) sends a poll. Legend text
recoloured to the axis-note grey instead of near-black.
Map: the + / - overlay buttons are replaced by a single zoom button that toggles
a full-width zoom slider along the bottom of the map (tap again to hide); the
chosen level is persisted across reboots and wins over the first-open auto-snap.
New 'Night mode (invert)' toggle in Map options inverts tile colours at render
time only (cache untouched), persisted.
Snake: pause/resume button next to the close X.
Status bar: hold for 3 s to capture a full-screen screenshot to
/screenshots/<time>.bmp on the SD card (16-bit BMP — fastest viewable format;
the hold suppresses the control-center tap).
Prefs: cfg v5 adds map_night + map_zoom.
