* feat(engine): drawElementImage capture service
* feat(engine): 3D projection + compositor-effect risk gate
* fix(engine): gate filter drop-shadow wherever blur gates (review)
detectCssEffectRisk documented drop-shadow as a ~29dB damage case but only
detected blur( in its three scan paths — a drop-shadow comp stayed on the
fast path despite the gate's own correctness contract. Detect drop-shadow(
in computed styles, stylesheet rules, and GSAP tween vars, pinned by a
focused test that runs the real page-side closure against a DOM shim
(computed / stylesheet / tween coverage + blur regression + effect-free
null).

* fix(engine): document HF_FORCE_DRAWELEMENT as diagnostic-only; make armStaticDedup idempotent (review)
Addresses miguel-heygen's blockers on #1919:
- HF_FORCE_DRAWELEMENT promoted from a stale "SCRATCH/Uncommitted" comment to
a documented diagnostic flag: it exists for upstream-Chromium repro work
(gate-vs-API isolation, crbug 521861819 149-vs-151) and R&D on gated effect
classes; renders under it may be damaged BY DESIGN since it bypasses gates
whose thresholds encode measured damage. Never production; the safety-net
blank guard also stands down under it so diagnostic frames arrive unmodified.
- armStaticDedup is now idempotent: the drawElement init path arms dedup
before canvas injection, then initializeSession called it again — the
second run overwrote the armed state with skipReason="capture_mode"
(captureMode is "drawelement" by then), producing contradictory telemetry
(armed frames + a skip reason), and re-ran the verification seeks on the
fallback path. It now no-ops once staticFrames or a skip decision exists.

* fix(core): drive adapter seeks when composition has no GSAP timeline
renderSeek returned early when deps.getTimeline() was null, skipping the
onDeterministicSeek call that drives all frame adapters (CSS, WAAPI,
Lottie, Three.js). That meant compositions using any non-GSAP animation
primitive froze on their initial frame during capture.
Now we still quantize the seek time and fire onDeterministicSeek even
without a timeline, so each adapter gets a chance to advance.
GSAP compositions are unaffected — timeline-driven seek still takes the
same path it did before.
