The "Send to HyperFrames" authoring guide is an internal contract for the Claude
Design import flow, delivered exclusively by the get-send-to-hyperframes-guide MCP
tool (raw server-side fetch of the .md, returned as tool-result data). The llms.txt /
web_search discovery path it was published for is no longer used. Drop it from
docs.json so it stops appearing in the public product docs nav + llms.txt; keep the
.md file at its path (the tool's raw fetch URL depends on it) and the redirect note in
claude-design-hyperframes.md (points at the raw URL, not the docs page). Orphan guide
files build cleanly here (claude-design-hyperframes.md already is one).

* refactor(lint): route asset-src skips through a shared isUnresolvedAssetPlaceholder predicate
Follow-up to the templating-token fix. The __UPPER__ + templating-token skip was
copy-pasted across the asset-src sites and had drifted: two non-lint sites carried only
the __UPPER__ half, and htmlCompiler's comment still claimed it "matches lint's skip"
after lint's skip became a superset. Extract one isUnresolvedAssetPlaceholder(rawSrc) in
@hyperframes/parsers/asset-resolution (both placeholder shapes, checked on the raw value)
and route every site through it: the four project.ts lint sites, hevcPreviewLint, and the
two previously-missed post-substitution sites (studio-server mediaCodecMap, producer
htmlCompiler). Remote/inline handling stays per-site (audio uses a narrower check).
Behavior-preserving for the lint sites (full suite green); the two non-lint sites are
post-substitution so they don't false-positive today, but now share one definition and
can't drift again. Adds unit tests for the predicate.

* docs(parsers): refresh hasUnresolvedTemplatingToken aside for the shared predicate
The parenthetical said the __UPPER__ shape keeps its own inline check at each call
site; this branch folded it into isUnresolvedAssetPlaceholder, so point there instead.
Addresses review nit.

* fix(lint): don't flag unresolved templating-token asset srcs as missing
The asset-src rules (audio_src_not_found, missing_local_asset, CSS url(),
and data-composition-src) treat any src that isn't a remote URL or an
__UPPER__ placeholder as a resolvable local path and error when the file
is absent. But the linter runs before any build/templating step, so a src
that still carries a late-bound templating token (<<token>>, {{ token }},
${token}) cannot be resolved statically and is not a missing file.
Add a shared hasUnresolvedTemplatingToken() predicate (alongside the
existing __UPPER__ tolerance) and skip such srcs at each asset-src site,
so unresolved templating tokens no longer surface as false-positive
"file not found / the rendered video will be silent" errors.

* fix(lint): check raw src for templating tokens before cleanAssetUrl; cover video/img/css + hevc
Addresses review. At the <video>/<img>/<source> and CSS url() sites the token skip
ran AFTER cleanAssetUrl(), which splits on ?/# and truncates inside a ${...} expression
(e.g. `${asset?.url}` -> `${asset`), so those sites still emitted the missing-asset
false positive for valid unresolved templates. Move hasUnresolvedTemplatingToken() onto
the RAW value at both sites, and extend the same skip to hevcPreviewLint (same
pre-substitution, cleanAssetUrl-first shape). Add regression tests for video/img/css
(including ?/# inside ${...}) and clarify the predicate docstring.

* docs(send-to-guide): enhance turns are free; render is the paid step
The shipped pricing model is import + enhance turns free, only the final
render charged (a monthly free-render credit, then per-minute). The guide
labeled enhance as 'the paid step', which misstates the model to the
authoring agent. Move the paid label to Render.
* docs(send-to-guide): state the tiered render billing contract + pin it in the guide test
Address review: the pricing line must teach Claude the real tiered contract,
not a single universal free render. Per heygen-server usage_limits.py: FREE
accounts get 3 renders/month (then blocked, not billed); paid plans are charged
20 credits per rendered minute at completion. Enhance turns are free.
Also pin the invariant in sendToGuideContract.test.ts: assert Enhance=free /
Render=paid + the tiered figures, and a negative assertion blocking the retired
'Enhance ... paid step' wording from returning.
The Claude Design Send-to guide rendered at its URL but was an orphan — absent from the
docs nav and llms.txt, so it never surfaced as a fetchable search RESULT (only as body
text in another page's excerpt, which Claude Design's web_fetch rejects). Add it to the
Guides nav (→ llms.txt index) next to claude-design, and give it frontmatter title +
description for a clean entry. This makes the full guide discoverable + fetchable via
search, the reliable path since a URL named only in a tool description is not fetchable.
* docs(guides): resolve the fidelity contradiction (preserve substance, adapt form)
The guide called the rebuild 'lossy by nature' while the checklist demanded 'content
match the brief exactly', with no rule for what to preserve vs adapt. On a live import
CD kept fonts/palette/hero but genericized the source's real figures (2.4M signals/sec,
+240% spike) into vague phrases. Resolve around one principle: substance (real copy,
exact palette/fonts, distinctive figures/data, product names, signature visuals) is
preserved verbatim; only the form (static page to timed multi-scene motion) adapts.
* test(guides): pin the Send-to fidelity contract against silent regression
Address review on #2620: the resolved 'preserve substance, adapt form' instruction is
load-bearing LLM-facing prompt text, but validate-docs only proves syntax. Add a semantic
pin (mirroring packages/cli figma skillContent.test.ts) asserting the three positive
concepts are present and the two retired contradictory phrases ('lossy by nature',
'content match the brief exactly') cannot silently return.
* style(guides): oxfmt the Send-to fidelity-contract test
Wrap the readFileSync call to oxfmt form (printWidth 100); unblocks required Format + its
preflight/preview-regression cascade on #2620.
* docs(guides): redirect Send-to imports to the Send-to guide
Claude Design's only doc-discovery tool is web search, which ranks this Template-First
(Download-ZIP) guide first; the Send-to guide is not indexed, so Send-to imports get
authored against the wrong flow. A body link here lets CD's fetch of this page unlock a
fetch of the correct guide (its URL now appears in a prior fetch result).
* docs(guides): add Send-to redirect note to the Claude Design landing page
The /guides/claude-design landing page (claude-design.mdx) is the indexed nav page and
points only at the Download-ZIP instruction file; a Send-to author landing here got no
pointer to the Send-to guide. Mirror the redirect from claude-design-hyperframes.md.
* docs(guides): add Claude Design → Send to HyperFrames single-file import guide
Self-contained authoring guide for the 'Send to HyperFrames' MCP import path
(distinct from the download-ZIP flow): single self-contained HTML wire format,
the composition contract the importer validates, inline-brand-assets fidelity
rules (base64 data: URIs), no bundled/splash artifacts, keep-the-original-as-
reference, a complete worked skeleton, the animation-pattern catalog, and
determinism rules. Reviewed for technical accuracy against a known-good
imported+rendered composition.

* docs(send-to guide): assets must be resolvable (inline OR fetchable URL), not inline-only
Large media can exceed the import size cap, so "inline everything" is wrong for it,
and the import tool description now states "resolvable refs." Align the guide: inline
data: URIs preferred (fonts/images/logos — the only fully self-contained form), a
publicly-fetchable absolute URL allowed for large media, and explicitly forbid relative
paths / local-file variables / expiring-or-private hosts (the media-expiry trap).
