924 * Stagecraft: authored background staging (roll, gravity flips, zoom, palette, parallax

926 *
927 * Presentation only. Every motion value is a pure function of (level, world.t / world.x,
928 * decoded score envelope, tier). Nothing here writes World or enters exportLevel /
929 * replayLevelContent. The camera acts on the low-resolution background raster only:
930 * hazards, player, ground, roof and the DOM HUD are never rotated, zoomed or tinted.
931 * Tier off, and reduced motion (the in-game setting or the system preference, read live every
932 * frame), resolve to null, which is the V2.12 drawing path.
933 * Outside a run (menu, stage select, settings, loading, calibration) the background only sways
934 * +-1.5 deg (Subtle +-.6 deg) on a 16 s sine: no layers, zoom or phrase colour. Any change of pose
935 * source (menu -> run, arming probe -> run, run -> menu, off -> on, a new run after death / retry /
936 * checkpoint) hands over through a blend of at least 0.5 s, and every shown frame then passes a rate
937 * guard, so roll <= 60 deg/s, zoom <= .3/s and light <= .2/s hold on every path, not only inside plans
938 * (stageShow). The audio kick (a <= .02 zoom pulse) rides on top and is not choreography.

1281 * Runs. Every run (a new app.runToken: a new attempt, retry, checkpoint or resume) starts at the player's own level (Stage
1282 * motion, Low graphics) with a clean slate: no level, cap, hold or trial carries over. Across runs the painter keeps only
1283 * the trial log and a hint (prior: earlier runs, and how many of them produced hard evidence). The hint is read by the
1284 * pre-flight check alone (a prior hard verdict makes it choose leans); it never sets a level, so no run starts Off.
1285 * Measurement. Every 30 play frames, once the last 45 frames were all drawn at the level in force (a level change or a
1286 * blend restarts that count, so no decision rests on frames of the previous level), it reads the draw p90 (dq) and median
1287 * (dm) and the median frame interval (fm) of those 45 frames. The run's first check records its opening baselines: the
1288 * frame median (fiBase, never above 60 Hz) and the draw median (dmBase). The frame line is max(22 ms, 1.5 x fiBase + 4 ms):
1289 * a 120 -> 60 Hz switch (16.7 ms) never crosses it, a halved 60 Hz frame rate (33 ms) does.
1290 * Trial. Over budget (dq > 14 ms, or fm over the line) steps down one level and measures again there, one level at a time
1291 * while the miss lasts. Frame intervals alone never take the stage below Subtle: a frame-only miss at Subtle starts no
1292 * trial, a frame-only trial stops at Subtle, and any trial only steps from Subtle to Off while the draw is still over
1293 * budget. The stage is only blamed when a lower level measurably helped against the level that missed:
1294 * - hard (draw misses only): the missing level's draw median had risen >= 1.5 ms above dmBase and was above 11.2 ms, and
1295 *   the lower level cut it by >= 0.5 ms. The only evidence that strikes: two hard verdicts against a level cap the run below it.
1296 * - draw (the median fell >= 0.5 ms, but the cost was already there at the opening, or the median

1296was <= 11.2 ms) and tail
1297 *   (the p90 fell >= 1.5 ms back within budget while the median held: a costly layer phrase, or the end of a spike): the
1298 *   lower level is kept and the level above retried after 8 checks with the draw within budget (doubling to 32; frame
1299 *   intervals do not hold a retry back: a host that stays slow must not keep the stage down). Never a cap.
1300 * - frame (the frame median fell >= 4 ms from above the line): outcome 'held', never 'kept', never hard, never a cap: frame
1301 *   intervals also stretch for reasons that have nothing to do with the stage (the host, other tabs, heat), and a step
1302 *   down can coincide with the host recovering. The lower level is held for 32 checks (doubling to 128 on each later
1303 *   frame hold in the run), then comes back one level at the first check whose 45-frame median is within 2 ms of fiBase
1304 *   (a display faster than 60 Hz counts as 60 Hz here). A hold ends early, restored like a trial without help, as soon as
1305 *   the held level stops beating the missed level by 4 ms while frames are over the line (or once the hold has run).
1306 * - No measurable help (for a frame-only miss only a frame gain counts), even at the floor: the trial restores the level
1307 *   it started from and holds off new trials for 32 checks (doubling to 128); only a draw miss whose p90 climbs another
1308 *   1 ms may start one sooner.
1309 * A switch between the full and subtle plans only starts when the two plans stay within 40 degrees of each other for the
1310 * whole 1.5 s blend, so a governor change never cuts a flip in half. User-visible result of a step-down: 3->2 the flow
1311 * layers (rays, streaks, mid skyline, prism) fade out within 0.25 s; 2->1 motion blends to Subtle over 1.5 s; 1->0 blends
1312 * to a still background. Every trial, its evidence and its outcome is logged in the DEVICE CHECK report (stageReport). */

1660/** Enemy drawing, kept out of paint.mjs so it merges beside other paint work. Bodies are rasterised
1661 * once per (kind, frame, facing, telegraph, low, scale) and blitted; shots are one arc each. Every pose
1662 * comes from the pure functions core.mjs collides with, and every drawn body covers its 3px-inset hurt
1663 * box (rounded corners of radius 8 stay outside it), so what is drawn is at least what kills.
1664 * Colour roles (readability contract): crimson = an enemy or a roller you jump; cobalt = a high shot,
1665 * stay down; white flash = it acts within one beat. None of these is a portal, coin, pad, orb or theme
1666 * accent colour. Cobalt #294cff replaced the V2.14 draft's violet, which sat 10 deg from the spider gate
1667 * (#c691ff): cobalt is >= 52 CIELAB dE from the spider gate for normal, protan and deutan vision (violet
1668 * was 35) and >= 114 from the crimson roller (violet 99). Both shot fills sit on skies of similar
1669 * luminance, so each shot carries a white 2.5px ring (>= 3.45:1 against every theme sky at shot height,
1670 * stage hue offsets included) and the high shot a white down-arrow (5.9:1 on cobalt).
1671 * Presentation only; the page also highlights, without any blinking, the enemy or shot named by
1672 * world.death once the run is over. Prefixed names: build.mjs concatenates every module into one scope.
