580 stories across 14 libraries: radix-ui, shadcn-ui, base-ui, react-aria,
ark-ui, mantine, headless-ui, intent-ui, reui, elevenlabs-ui, starwind-ui,
webcoreui, and web-awesome at full documented coverage; mui at 114/128 with
the MUI X Pro/Premium components recorded as explicit commercial-license
gaps. react-bits and Aceternity UI stay preview-unavailable under their
source-redistribution terms.

Story runs land as per-library modules merged in data/preview-stories and
components/preview-stories, with scripts/check-story.mjs as the per-chunk
gate and a catalogue-wide coverage test that requires a story or a named
justified gap for every documented component. Library stylesheets (Mantine
stack, webcoreui Sass, Web Awesome) load with the preview routes only.
