New:
- Flight logbook safety net: disabled by default, requires confirming
a full-screen warning before it can be turned on, and automatically
switches off again after exactly 24 hours - survives restarts and
power cycles (no valid enable timestamp = guaranteed off). Each
activation now writes its own CSV file instead of endlessly
appending to one growing file, and every file can be deleted
individually from Logbook files.
- Adjustable display brightness (10-100% in 10% steps, Menu -> System
-> "Brightness") with a live preview.
- About screen (Menu -> System -> "About") showing project name,
description, and firmware version.
Fixed:
- Radar's red altitude band (>9100m/30000ft) no longer gets dimmed at
night - the previous dim tone looked orange-brown and was hard to
tell apart from yellow. Legend and markers are consistent again.
- Radius change no longer leaves a stale "tail" trail behind each
aircraft between the old and new position.
- Splash screen no longer shows a time-of-day greeting that appeared
too late in the boot sequence to be useful; the star animation now
starts immediately instead of only near the end of boot.
- Clock stayed on raw UTC after the first boot instead of local time
(missing DST handling in some timezones) because the location wait
loop skipped the timezone lookup once a location was already saved.
- Header clock no longer leaves stale digit fragments behind the
current time, most visible on the last minute digit.

Adds FlightLogbook::todayMaxAltitude(), which scans today's logbook
CSV for the entry with the greatest altitude at first sighting, and
displays it as "Highest flight today: <callsign> (<alt> ft)" on the
Statistics screen (Menu -> Flight Options -> Statistics).
Also documents the CYD-flightradar.bin rename step (for GitHub
release uploads) in the CLAUDE.md release workflow.
