/* ---------------- the frame watchdog (the King's freeze, 2026-10-14) ----------------
 * The master frame once had no witness: the Perf Meter pulses on its
 * own loop, the citizens keep their own interval, the music rides the
 * media pipeline — so when a phone starved this loop (or the canvas
 * lost its context), every instrument read healthy over a frozen
 * picture, and the code went on believing the King was running. The
 * watchdog keeps time on an interval — the clock that provably
 * survives — and answers for the frame: if the pulse goes stale while
 * the King is in his city, it re-kicks the frame chain, asks the
 * canvas for its context back, and, should animation frames stay
 * starved, drives the frame itself at a limp-home cadence until the
 * browser resumes. Every stall is written to the build memory. */
