Format Spec
<!-- GENERATED by @poopdeck.gl/core renderCapabilitiesMarkdown from each backend's
BackendDescriptor. Do not edit by hand — regenerate with
`node scripts/gen-capabilities-doc.mjs` (see that file's header for the
build-first invocation) whenever a BackendDescriptor changes. CI runs the
same script with `--check` and byte-compares its output against this file,
so drift fails the build instead of rotting here. -->
