// Tap rect of the back button BaseTheme::drawHeader paints on touch boards.
// The header's FreeInkUI frame is non-interactive, so the rect is recorded
// here at draw time and consumed by MappedInputManager's Back mapping; every
// screen that draws a titled header gets tap-to-go-back without its own
// routing. Cleared on activity exit (and by headerless draws) so a stale rect
// never eats taps on a new screen. Written by the render task and read by the
// loop task; a torn int read at worst misroutes one tap on a band that is
// being redrawn, so no lock is taken.
