Detailed Description

RAII critical section against the control tick and everything below.

Raises BASEPRI to kBasepriCeiling (Level::ControlTick) for its scope and restores the previous value on exit. Safe to nest. Handlers above the ceiling — audio, USB/MIDI, other DMA — are unaffected by construction.

Use it around any multi-word state shared between main and the control tick. Do not use it from a handler above the ceiling (that handler must not touch such state at all), and do not reach for PRIMASK instead.
