Summary

  • True partial present (row DMA of dirty rects) + glyph-local time present
  • Cache Wi-Fi bars / status icon decode; colon MOTION only on fade change

Test plan

  • idf.py build
  • Device: pack resident, present ~17×59 / ~2KB SPI at DEBUG_LEVEL=2
  • Smoke FACE with seconds after merge

Stream only dirty glyph/colon bands to the panel, cache Wi-Fi bars and
status icon decode, and skip empty colon MOTION ticks.
