* fix(cli): distinguish a skipped browser check from a genuinely clean one
`hyperframes check`'s runtime/layout/motion/contrast JSON sections reported
the exact same ok:true/zero-findings shape whether the browser session
actually ran and found nothing, or never ran at all (a blocking lint error,
a lint-step crash, or an exception thrown before the audit could start all
took the same "empty result" fallback). Only the top-level ok field and an
undocumented layout.duration === 0 tell separated the two cases apart.
Add a skipped boolean to CheckBrowserResult, set at the only two places one
is constructed (false in the real audit result, true in the empty-result
fallback), and mirror it to a new top-level browserSkipped field on
CheckReport. The human-readable report now prints a warning when the
browser never ran; the JSON envelope carries the same signal for callers
that only check individual sections.

* fix(cli): fingerprint textual sweep state
* fix(cli): share one motion classifier between sweep guard and liveness
The frozen-sweep guard (sweep_static) and keepsMoving liveness (motion_frozen)
each owned their own definition of "what counts as motion": the sweep
fingerprint in layout-audit.browser.js read nine channels while
motion-sample.browser.js compared box + opacity only. They meet in one decision
in checkPipeline.ts, so a fixed-width attr() countdown was accepted by the
sweep guard and still reported frozen by liveness.
Move the classifier into motion-signature.browser.js, injected before both
samplers, and make it the single owner:
- Per-element channels (box, opacity, font-variation axes, clip-path, direct
text, form-control state, ::before/::after content, media pixels) as a
reader list so further channels (e.g. SVG dash) plug in.
- Liveness consumes the same signature with 2px / 0.08 bucketing; the sweep
guard consumes it exact. motion-sample throws at install if the shared
script is missing.
- Counter state is a composition-level channel over box-generating elements
and root ancestors. display:none subtrees generate no boxes and are
excluded, and only declarations naming a counter that some painted
generated content (::before/::after/::marker on a non-ignored, paintable
host) consumes are folded in, so a decoy hidden counter cannot make a
frozen composition read as live.
- clip-path is a channel, replacing the fingerprint's former reliance on the
clipped-away visibility probe, so a wipe over a static box still counts.
- data-layout-ignore layers are excluded from the signature but not from the
per-selector `visible` bit reported for explicit motion assertions.
- Root resolution for the "*" liveness scope now matches the sweep guard and
the root element is part of its own signature.
Tests: motion-signature.browser.test.ts (happy-dom, per-element fake computed
style so ancestor handling comes from the classifier) and
motion-signature.browser.chromium.test.ts (real Chromium via puppeteer-core;
skips without a system browser) pin every branch: attr() substitution,
display:none decoys, named-counter gating, ::marker, zero-box hosts, ancestor
counters, textarea/indeterminate, root text, clip-path, ignore layers, and
sweep/liveness agreement on the countdown fixture.

* fix(cli): prune unrendered content from the motion signature and measure asserted scopes
The shared motion classifier pruned only display:none subtrees, so text,
pseudo content, media pixels, and counter decoys inside skipped
content-visibility contents changed the frozen-sweep and liveness
signatures although nothing painted. Pruning is now platform-owned where
checkVisibility exists (display:none, skipped hidden/auto contents; a
display:contents host keeps its painting pseudo-elements), with the
computed-style fallback for happy-dom. A content-visibility:hidden host
signs its own box, opacity, clip-path, font axes, and widget state, but
not its text, pseudo content, control value, or media pixels; hosts where
size containment does not apply (non-atomic inline, display:contents,
table and internal table boxes, ruby) skip nothing. isVisibleElement
regains the checkVisibility floor layout-audit uses on its opacity-floor
path, so an asserted selector inside skipped contents reports hidden.
The layout-audit opt-out no longer applies to the element passed as the
signature root: a keepsMoving scope that is itself data-layout-ignore is
measured (an assertion naming an element outranks the opt-out) instead of
producing an empty signature that motionAudit reports as a missing
selector. Opt-outs inside the scope still apply.
motion-sample defers the missing-classifier error to the first call so
the driver's evaluate surfaces it instead of an opaque "is not a
function" page error; round() is shared.
The real-Chromium suite is opt-in on Windows (HYPERFRAMES_BROWSER_TESTS=1):
in the shared Windows package lane the runner's Chrome did not launch
within the package hookTimeout, and the suite already runs on Linux CI
where the system Chrome is found. The launch hook has its own 120s ceiling.

* fix(cli): prune display:contents in skipped contents; table-cell skips, caption paints
A display:contents child of a content-visibility:hidden host has no box
of its own, so the platform check could not tell it apart from an
ordinary display:contents owner and it stayed a counter consumer: a
change of the owner's counter-reset altered the sweep signature although
nothing paints. The parent's skipsContents verdict now prunes it; boxed
descendants keep being decided by the platform.
NOT_CONTAINABLE_DISPLAY had table-cell and table-caption inverted
versus Chromium 152, where a table-cell host skips its contents and a
table-caption host paints them.
Four Chromium pins: the display:contents-in-skipped-contents counter, a
table-cell host's own text and pseudo content (frozen), a table-caption
host's own text and pseudo content (motion), and a counter reachable
only through a skipped host's hidden ::marker / ::after (frozen; also
asserts the skipped child is not visible for motion-sample).

Since v0.7.71 (#2763), gsap_infinite_repeat demotes to a warning when the
root declares a finite data-duration: deterministic seeking and export clip
to that explicit window. Without one it remains a hard error (unbounded
timeline duration breaks render planning).
Update every doc site that still teaches the old absolute ban — the core
determinism contract, the animation adapter notes, and the design-guide
tables/checklists — to state the bounded allowance and keep the finite-count
formula for loops that must end before the composition does.
skills/hyperframes-animation/rules/ambient-glow-bloom.md is intentionally
untouched: its shimmer must stop before the composition ends, which is
exactly the case where a computed finite count is still required.

A rate lane skipped Web Audio entirely, so a ramped video or audio clip in a
group played native output without the group's fader, mute or FX while the

curve; the media-element capture can, so the skip now guards that fallback.

* feat(cli): add hyperframes clean to find and remove what HyperFrames left on disk
`hyperframes clean` lists leftover render work dirs, debug renders, the history of projects
that no longer exist, idle video proxies and extracted video frames, with sizes, and removes
them. `--dry-run` removes nothing, `--json` is for agents, `--snapshots` also removes

.tmp-<uuid>-<proxy name>; nothing else is swept.
* style(producer): keep a renderDirOwner doc comment within 120 columns
* feat(player): play and loop a range of the film with range-start and range-end
The runtime takes a set-play-range control and stops on the range end frame itself.
The player wraps to range-start with loop, fires ended without it, and reports a
range cut to the film with rangeclamped. Video and __timelines players check it per tick.
* fix(player): hold a range on its last frame and let the runtime own range jumps
A runtime with the play-range capability jumps to range-start itself when a new range leaves
the playhead outside, so a stale state no longer ends the film; older runtimes keep the
player fallback, guarded until a state lands inside. Every range stop shows the last frame
before range-end; a paused playhead re-parks only when it falls outside the new range.
* fix(player): stop a range a check early and enforce its end on a video in a background tab
