Implementation screenshots as release evidence
A screenshot is useful when it identifies a real implemented surface and keeps its limits attached. This release uses the existing neutral publishing fixtures plus captures from two read-only demos, serves them through responsive picture sources, and gives each chosen page one canonical image for metadata and sitemap discovery.
3 renderer outputs · 2 read-only demo captures · WebP plus PNG fallback · explicit dimensions
Start with an implemented surface
The available public evidence came from two places: three neutral outputs produced by the working static renderer set, and two public demos derived from working operations applications. The captures therefore show software that exists rather than a speculative mockup.
The publishing fixture uses neutral Northstar Reference material. The food and finance demos use synthetic records and disable every persistent action. Those boundaries make the screenshots publishable without turning private records into marketing assets.
Keep the claim inside the frame
A renderer screenshot proves that the renderer produced that public experience. A demo capture proves that the read-only interface, navigation, and displayed calculation state exist in the exported demo. Neither image proves production concurrency, recovery, ranking, traffic, conversion, or revenue.
The caption carries that distinction beside the image. It is part of the evidence contract, not decorative copy below a generic hero.
- Name the implemented surface in the alt text
- State whether records are neutral, synthetic, or private
- Attach the current boundary in the visible caption
- Link the image back to the canonical system, case, or note
Deliver one image without forcing one format
The reusable picture template publishes WebP sources and a PNG fallback. The source image dimensions remain explicit so the browser can reserve the correct layout space before decoding, while a 720-pixel WebP candidate avoids sending the full desktop capture to every narrow viewport.
Format variants are delivery derivatives, not separate evidence. The canonical PNG remains the stable image named in structured metadata and the image sitemap.
Make image discovery follow page ownership
Only pages with a meaningful raster evidence image receive an ImageObject and image-sitemap entry. Each selected URL lists one canonical image rather than every WebP derivative or every screenshot used further down the page.
The social preview is a separate 1200 by 630 raster assembled from the same real interfaces. It is optimized for link previews; it is not allowed to replace the page’s canonical evidence image.
What the implementation proves
- Three retained 1440 by 1100 renderer outputs from the neutral publishing fixture
- Two captures produced from the existing read-only food-operations and private-finance demos
- Reusable picture markup with WebP candidates, PNG fallback, dimensions, alt text, captions, and loading policy
- One canonical raster image per selected page in ImageObject and image-sitemap metadata
Real surfaces, explicit boundaries, responsive delivery.
Every image identifies what was captured, where the public data came from, and what the capture cannot prove.
Artifact, implemented fact, and limit.
The screenshot stays useful because its provenance and boundary remain visible beside it.
| Record | Implemented use | Boundary |
|---|---|---|
| Renderer output | Radiant, Signal, and Atlas show three implemented public architectures using the same neutral reviewed source library. | They do not prove search demand, indexation, ranking, traffic, or editorial quality. |
| Food demo capture | The screenshot comes from the exported five-screen food-operations demo with its implemented navigation and calculations. | Records are synthetic; persistent actions, production storage, permissions, and recovery are excluded. |
| Finance demo capture | The screenshot comes from the exported five-screen household-finance demo with its multi-currency overview. | Records are synthetic; it is not a banking connection, accounting product, or production-load result. |
| Responsive delivery | The same evidence image is available as WebP candidates and a PNG fallback with explicit intrinsic dimensions. | Compression and responsive markup improve delivery; they do not make the evidence stronger. |
Limits: The captures show public fixtures and read-only demo state, not private production records. · Interface evidence cannot establish acquisition or business outcomes. · Image-sitemap inclusion helps discovery but does not guarantee crawling, indexing, image results, or traffic.
