New poiesis-printer-chromium crate — headless Chromium bridge via CDP for HTML→PDF rendering (B-003).

Changes

  • print_to_pdf(html, opts) -> Result<Vec<u8>> converts an HTML string to PDF bytes via chromiumoxide 0.7
  • PrintOptions with widescreen_16_9() (254×142.875 mm), standard_4_3() (254×190.5 mm), and from_aspect() routing on AspectRatio
  • Binary discovery: CHROMIUM_PATH env → which() for chromium/chromium-browser/google-chrome/google-chrome-stable
  • chromium feature (default-on) gates all CDP deps; compiles clean with --no-default-features
  • Soft dep: requires system Chromium (apt install chromium / brew install --cask chromium)
  • RUSTSEC-2025-0052 (async-std unmaintained via chromiumoxide 0.7) suppressed in audit.toml and deny.toml

New `poiesis-printer-chromium` crate — headless Chromium bridge via CDP:

- `print_to_pdf(html, opts) -> Result<Vec<u8>>` converts an HTML string
  to PDF bytes using a system Chromium browser via chromiumoxide 0.7.
- `PrintOptions` with presets: `widescreen_16_9()` (254 × 142.875 mm),
  `standard_4_3()` (254 × 190.5 mm), and `from_aspect()` routing on
  `AspectRatio`.
- Binary discovery: `CHROMIUM_PATH` env → `which()` for chromium,
  chromium-browser, google-chrome, google-chrome-stable.
- `chromium` feature (default-on) gates all CDP deps; compiles clean
  with `--no-default-features`.
- Soft dep: install script note — requires system Chromium.
- Advisory RUSTSEC-2025-0052 (async-std via chromiumoxide 0.7) suppressed
  in audit.toml and deny.toml; no upgrade path while pinned to 0.7.

Gate-Passed: kanon 0.1.3
