* fix(skills): clear Snyk findings and harden supply-chain surface
Address the security-audit findings on the published skills with no change to
any skill's behaviour.
- media-use: resolve.test.mjs runs resolve.mjs via execFileSync with an argv
array instead of execSync(`node … "${tmp}" …`), removing the command-injection
(CWE-78) sink that drove the Snyk Fail.
- music-to-video: replace dynamic `element.innerHTML = <var>` with a setSvg()
helper (DOMParser image/svg+xml + importNode, text fallback) in the
intro-kinetic-cascade and logo-split-lockup-pulse frame templates, clearing the
DOM-XSS (CWE-79) Snyk Fail. Renders identical SVG.
- pr-to-video: fetch-people-avatars.mjs refuses any avatar URL that is not https
on a GitHub avatar host (SSRF guard) and only writes under the project dir
(path-traversal guard); best-effort, always-exit-0 behaviour is unchanged.
- embedded-captions: pin `uvx --from whisperx==3.8.6` (overridable via
$WHISPERX_VERSION) so transcription no longer resolves "latest" at runtime.
- gsap: add Subresource Integrity (integrity + crossorigin) to the 8 render-time
CDN GSAP <script> tags across embedded-captions, music-to-video,
faceless-explainer, pr-to-video and product-launch-video.
- hyperframes-animation / hyperframes-creative: document package-loader's
defense-in-depth and note that the installLine strings are display-only.
Verified: media-use resolve (12/12), probe injection (1/1) and manifest (19/19)
tests pass; avatar host-allowlist checks pass; all changed JS passes node --check
and oxfmt.

* docs(skills): clarify product-launch-video vs website-to-video routing
Sharpen the router's product-vs-site decision in hyperframes/SKILL.md: the
split is now "is the site selling a product?" — yes (SaaS / app / product /
company site) → /product-launch-video (a promo; the default for any commercial
URL, even if the site is only named); no, or the user just wants the site shown
as-is (portfolio / blog / docs / personal / event) → /website-to-video (a tour).
Updates the workflow table, the disambiguation bullet, and both workflows'
Input/Output blurbs to match.

* style(skills): satisfy oxfmt in the two music-to-video templates
The CI Format job runs `oxfmt --check .`, which also formats embedded <script> in .html. Reflow the setSvg() blocks added for the DOM-XSS fix to oxfmt's wrapping — no logic change. Regenerate the music-to-video manifest hash to match.

* fix(skills): sanitize SVG in music-to-video templates (real CWE-79 fix)
Addresses @Magi's review: the previous setSvg() only swapped the sink
(innerHTML → DOMParser + importNode) but did NOT sanitize, so active SVG
content still executed on insertion into the live document. Verified in
headless Chrome that the old shape fired both an svg `onload` handler and an
inline `<script>`.
setSvg() now runs a default-deny cleanSvg() over the parsed tree before it ever
enters the document: only an allow-list of inert drawing elements
(svg/g/path/line/rect/circle/… ) and presentation attributes
(d/fill/stroke/viewBox/…) survives. Every other element (`<script>`, `<image>`,
`<use>`, `<foreignObject>`, `<a>`, `<animate>`, …), every `on*` handler, and
href/xlink:href/style are stripped — on the root node too. Non-SVG or malformed
input still falls back to textContent.
Trusted content (the bundled icon library + the default spark/cloud marks)
renders byte-identically; only hostile markup in vars.icon / leftMark / rightMark
is neutralized.
Browser-verified (headless Chrome, both templates' helper):
old setSvg → fired ["script","onload"]
new setSvg → fired [] · trusted icon still renders · 0 danger nodes · 0 on* attrs

The kinetic-letter-in motion-primitive (a music-to-video reference authors copy)
animated the word's letterSpacing as a settle — a reflow tween that micro-stutters
under seek-by-frame capture, and outside the registry scan so the rule never fired
on it. The chars are already per-glyph spans, so migrate the settle to a per-glyph x
spread ((0.04em − −0.04em) × 280px = 22.4px/gap, centered about index 3), with a
comment naming the hazard and the rule. Render-verified: faithful, smooth.
Document two intentional design choices in gsap_non_transform_motion so future
readers don't read them as misses:
- No per-line/per-file suppression by design — the stance is fix-the-motion, not
silence-the-rule; every plain-DOM case has a faithful transform equivalent.
- set() is skipped intentionally: a set() that seats an integer-snapped layout
position before a later transform tween is a single from-state frame, not motion.
Also hoist loadParseGsapScript() above the per-script loop (the other async rules
do the same; dynamic-import cache makes it equivalent, but the placement no longer
reads as load-bearing).

Replace bgm-to-video, bgm-to-video-new, bgm-to-video-refactor, and the
standalone beat-sync/montage skills with a single music-to-video skill.
