* feat(registry): add cinemagraph — a still photograph with one living region * feat(registry): add ai-answer-rank — a mock AI answer that re-ranks to put your brand in it A 1080x1080, 9s block for answer-engine and AI-visibility marketing. A prompt types into a chat card, the assistant answers with a ranked list of three picks, then re-ranks: the promoted brand slides into its slot (brandRank 1-3), the picks below step down, the third fades out of the list, and the brand row lands with the one accent highlight and a drawn check. Monochrome placeholder UI; prompt, lead-in, pick names, brand, rank, accent, ink and ground are variables. * feat(registry): add caret swap text effect * feat(registry): add pendulum-swing component Add a motion-primitive component that hangs content from a fixed pivot and lets it settle with a damped oscillation, like a hanging sign coming to rest on its hook. The swing rides a single unitless custom property (--hf-swing-angle) that the timeline eases 1 -> 0, so only rotation animates and it stays sub-pixel under the seek-by-frame capture engine. The demo drives it with a damped-oscillation ease (a cosine inside an exponential decay, normalised to land exactly upright) so the sign passes through center several times, each pass smaller, before it rests. Four enum variables: pivot (top-center/left/right), amplitude (gentle/standard/wide), direction (right/left), tone (ink/paper/accent, each a bg/fg pair to keep AA contrast on any frame). The snippet is recipe-only and does not own its timeline; its demo carries the same variable declaration. Ran npx hyperframes lint/validate on both files, regenerated registry.json via scripts/generate-registry-items.ts and the docs via scripts/generate-catalog-pages.ts. * fix(registry): drop hand-added cinemagraph index entry; catalog-publish adds it * style(registry): format pendulum-swing with oxfmt * fix(registry): keep pendulum-swing demo caption clear of the swinging sign * fix(registry): ship the ad-template editing contract for ai-answer-rank --------- Co-authored-by: Carlos Miranda Levy <carlosmirandalevy@gmail.com> Co-authored-by: tugrawork-creator <319556794+tugrawork-creator@users.noreply.github.com> Co-authored-by: Akshar Patel <aksharcommit@gmail.com> Co-authored-by: rottenpen <12029924+rottenpen@users.noreply.github.com>
