* The `companies:` frontmatter vocabulary, shared by its writer
|
||
* (`apps/cli/sync.ts`, from the local DuckDB company-frequency database), its
|
||
* schema (`blume.config.ts`) and its two readers: the company table under a
|
||
* problem page's badge row (`components/ProblemBadges.astro`) and the
|
||
* Companies section of the Appendix (`pages/appendix.astro`), where each
|
||
* company's card — anchored at `companyHref()` — lists the problems it asked.
|
||
* Plain data, no Astro imports: sync imports this file under Bun.
