# HTML presentation vs PDF benchmark

This fixture compares one browser-ready HTML presentation with a PDF rendered from the same source.
It is evidence for the associated Slidesfly Blog article, not a general format-performance test.

## Reproduce the PDF

1. Serve this directory through local HTTP.
2. Open `source.html` in Chrome 151 or newer.
3. Confirm `ArrowRight` changes `1 / 3` to `2 / 3`.
4. Focus the button and press `Space`; confirm the text changes while progress remains `2 / 3`.
5. Print the page to PDF with background graphics enabled.
6. Inspect the output with `pdfinfo` and `pdftotext`.

The committed PDF was produced with Chrome 151.0.7922.174. Its metadata contains a creation time,
so a fresh export can differ by SHA-256 even when its visible content is unchanged. Use
`results.json` as the exact record for the committed artifact.

## Evidence boundary

The result verifies three pages, extractable text, and the absence of embedded PDF JavaScript in
this generated file. It does not establish PDF/UA or WCAG conformance, pixel parity, print color
accuracy, cross-reader compatibility, network performance, or audience outcomes.
