Search web font families by name/style

Search the Google Fonts web-font catalog by keyword. Returns matching font families (family name + category + available variants + a css2 stylesheet URL). DISCOVERY ONLY, and this is NOT the set the renderer can draw: a cloud render draws only the faces GET /v1/fonts lists, or a face sealed in a brand kit font asset. Naming any other family in captions/params fails validate_composition with font_not_reproducible. Read GET /v1/fonts to choose a family AND an admitted weight and style before authoring. Read-only and free; results are cached server-side. An empty `results` array means no match (or the upstream catalog was unavailable).

List the font faces the renderer can actually draw GET

The renderer's admitted font set: per family the exact name authoring accepts, the weight ranges a shipped file declares, the styles bytes exist for, the caption default weights, and whether the bytes are bundled or an aliased metric-compatible stand-in. Choose from here and validate_composition will not refuse the face. Unlike POST /fonts/search (which searches the GOOGLE catalog) this is what the render page can rasterize. `manifestVersion` identifies the exact table and moves only when the admitted set does. Covers the BUNDLED set only — a brand kit's sealed faces are per-org and per-render.

Cancel an async job POST

Cancel a running async job so an agent can abort a mis-priced/runaway operation without waiting out its TTL. Cancellation is durable and never meters. Already-terminal jobs are rejected (422 job_not_cancellable).
