Copies moq.pro's tools/cards generator (moq-dev/moq.pro#1701) for the moq.dev posts: Bun-style 1200x675 PNGs rendered with the devshell's Playwright Chromium via `just cards`. Only the open-source cards move; CDN announcements stay in moq.pro. Highlighting uses highlight.js directly (already a dependency) instead of svelte-highlight. The flake now exposes Playwright and a Chromium-only browser set, matching moq.pro's devshell. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

There was a problem hiding this comment.
When the repository is checked out beneath a directory containing spaces or non-ASCII characters, URL.pathname retains percent encoding (for example, /tmp/moq%20dev). Consequently the module-level readFileSync calls look under a nonexistent encoded path and every just cards invocation fails before rendering. Convert import.meta.url with fileURLToPath before passing it to dirname.
Useful? React with 👍 / 👎.

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. WalkthroughThe changes add twelve announcement-card definitions and a renderer that produces PNG images with Playwright Chromium. The renderer supports selecting cards by slug and saving HTML previews. The development shell configures Playwright paths and Linux browser options. A Just target and README document the rendering workflow, and Git ignores generated output. Priority: ⬇️ Low Merge Risk: 🔵 Low · up to Several published examples cannot be used as shown, and rendering fails from checkout paths containing spaces. These are bounded issues, but the examples and asset path should be corrected before the cards are published. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Make the noq dependency example valid TOML.
The card displays three assignments to moq-tokio in one [dependencies] table. TOML rejects a key defined more than once, so readers cannot use the example as shown. Keep one active assignment and show the other choices as comments or separate examples. (toml.io)

Decode the module URL before constructing asset paths.
If the checkout path contains a space or another percent-encoded character, .pathname retains the encoding. readFileSync then looks in the wrong directory, and card rendering stops before Chromium starts. Use dirname(fileURLToPath(import.meta.url)). (nodejs.org)
