/**
 * dev/classes-browser.test.mjs — the CLASS LAYER's trigger in a real browser,

 *
 *   node dev/server.mjs 8123 &      # the static dev server
 *   node dev/classes-browser.test.mjs
 *
 * What it pins (the freeze contract's other half — js/ui/ClassWindow.js's
 * screenshots live in dev/class-shot.mjs):
 *   · a plain boot asks for NOTHING (level 0, no class);
 *   · crossing data/shipScreen.json → level.classAt in a quiet sky opens the
 *     console by itself, once, through GameScene._classBeat (the same path a
 *     real run takes — no ?level5), and the world parks through _frozen;
 *   · dismissing it DEFERS: no class is filed, the world runs on, and the
 *     console never re-fires on its own;
 *   · the ship console's CHOOSE YOUR CLASS door is the way back in (its snapshot
 *     still reports mode 'choose' until something is filed);
 *   · locking a class in flips that snapshot to the class plate.
