Renders invoice PDFs inside the Worker with @formepdf/html (Rust layout engine compiled to WASM, web target, explicit init), stores the bytes in R2, and indexes invoice metadata in KV so the list persists. Plain static form UI served by Workers Assets; Hono routes for render, list, fetch and delete. Includes 10 vitest-pool-workers tests that exercise the real engine and bindings in workerd, a Playwright smoke spec, and a README that states the Workers Paid plan requirement (a render costs ~20 ms CPU, above the Free plan's 10 ms cap) and the measured cold/warm numbers.

0.20.1 fixes the worker entry's result shape (the layout-pass count declared in the package's types is now actually returned in workerd). Lockfiles regenerated with the templates CLI; template tests pass in workerd and a wrangler dev render was verified against the pinned version.

Description
Adds
invoice-pdf-template: a Worker that renders invoice PDFs from HTML + print CSS using@formepdf/html(WASM in the isolate, no browser), stores them in R2, and indexes metadata in KV. Includes a form UI, a JSON API, and a vitest-pool-workers suite (10 tests, run in real workerd).No linked issue - this is a new template contribution.
Lockfiles were generated with the repo's
templatesCLI;templates lint,lint-npm-lockfiles, syncpack, and prettier pass locally. The dependency is pinned to@formepdf/html@0.20.1.Per CONTRIBUTING.md I've omitted
