mangavalkandClaude Opus 5.5 a904615c51 Refresh effect per page 
Pages choose their own refresh effect (or the Hardware setting), used when
the page appears and for its own changes. Schedule blocks that switch
instantly and rules still switch instantly. The ESP32 sends page effects
to the Nano with a new no-save flag (E ...,2), so page switches don't wear
the Nano's EEPROM. Page format 7 (version 6 pages are converted).
