- brightness.py: BrightnessController + CLI, portiert aus DoDimmen_V/main.h (gleitender Mittelwert, Hysterese). Schwellen 300/2500 aus altem Code, Prozente 5/15/50/100 - verallgemeinert auf 4 Stufen: 100% jetzt erreichbar (alter Code max 50%); neue obere Grenze HELL_MAX=3500 (anpassbar), Rest wie im Original - run_display: --ldr bindet die Regelung in die Hauptschleife ein (sendet nur bei Stufenwechsel) - test_brightness.py: Schwellen, Hysterese, Mittelung - README dokumentiert die Regelung; .gitignore: Hardware/ Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
