 # VERSIONS:
+# V1.43 2026-07-20 Raised alarm-test pitch and capped volume at the proven 40% maximum
 # V1.42 2026-07-20 Changed tests to higher single-tone sounds and added a useful perceptual volume curve
 # V1.41 2026-07-20 Fixed raw alarm audio startup and buffering so tones play instead of amplifier clicks
 # V1.40 2026-07-20 Added ES8311 speaker output, persistent alarm volume and local speaker test controls

 # - The Snooze duration is a persistent Home Assistant configuration entity.
 # - Alarm speaker volume is persistent and adjustable from Home Assistant or the display.
 # - The ES8311 remains at its 75% / 0 dB reference while local PCM amplitude
-#   follows a perceptual 24 dB volume curve across the displayed 5-100% range.
+#   follows the proven perceptual curve across a deliberately capped 5-40% range.
+# - The 40% setting is the loudest available level because testing found it
+#   to be the practical bedside maximum for the fitted speaker.
 # - The Alarm Clock page provides local Beep, repeating Alarm and Stop hardware tests.
-# - Beep is a short 1800 Hz tone; Alarm repeats one 1600 Hz tone.
+# - Beep is a short 2800 Hz tone; Alarm repeats one 2600 Hz tone.
 # - Speaker tests generate audio locally and do not require Home Assistant or media files.
