Background and Goal

CS-13193. The host tool module moved from @cardstack/boxel-host/commands/screenshot-card to commands/capture-card in cardstack/boxel#6307. Both the demo card and commands/listing-create.ts import it, so they have to follow or they resolve to nothing.

Where to start

• screenshot-card-demo.gts → capture-card-demo.gts, class ScreenshotCardDemo → CaptureCardDemo, and the instance's adoptsFrom repointed at the new module.
• commands/listing-create.ts — the import path and the CaptureCardCommand symbol only.

Left alone on purpose

The catalog's own listing "screenshots" — the marketing images under each listing's Screenshots/ directory, the screenshots display vocabulary in listing.gts, and autoScreenshotExample in listing-create.ts — are a different concept that happens to share the word. Only the platform API references changed.

Testing

No remaining references to ScreenshotCardDemo, screenshot-card-demo, commands/screenshot-card or ScreenshotCardCommand. The Screenshots/ asset directories are untouched.

Must land together with cardstack/boxel#6307.

Copilot review overview

🔵 Needs a closer look

Update commands/listing-create.ts to consume the new command’s capture URL output.

Review effort: Lite
Findings: None

What changed in this PR

Renames the screenshot capture demo and updates host command references to the platform’s capture terminology.

Changes:

• Renames the demo class, module, metadata, and UI terminology.
• Updates imports and usage to CaptureCardCommand.
• Preserves catalog listing screenshot terminology.

A required fix remains in commands/listing-create.ts: it still reads result.imageDefUrl, but the new command returns capture URLs.

File	Summary
commands/​listing-create.ts	Updated capture command import and usage; output handling still requires correction.
CaptureCardDemo/​515e9c39-9f33-4597-99f4-6763f105d70e.json	Updated card metadata for the renamed demo.
capture-card-demo.gts	Renamed demo implementation and capture terminology.

Code review: one bug found (inline). The rename is correct and needed, because boxel main provides @cardstack/boxel-host/commands/capture-card and no longer has screenshot-card. But listing-create.ts still reads the old result shape, so auto-captured listing images silently stop working.

None of the changed files are in boxel's packages/catalog/test-subset.json, so the paired-branch and re-pin steps in AGENTS.md don't apply.

Bug: listings never get an auto-captured image. On boxel main, capture-card returns { captures: [{ name, url, width, height }] }. It has no imageDefUrl field. So imageDefUrl is always undefined here and autoScreenshotExample returns early without any error. Every listing created with an example card runs a full capture and then throws the result away. The as any cast hides the mismatch from the type checker.

The demo in this PR already reads result.captures[0]?.url, so swapping the import alone isn't enough. That URL points at boxel's media cache, not an image file in the realm. The code below that links the image into the listing's images field (linksTo(ImageDef)) needs rework as well: either save the capture into the realm as an image file, or change how the listing refers to the image.
