Open index.html locally. Four native selects choose a broad main form (mound/oval/ridge), near/wide gap, illustrative top/oblique view, and private/possible desk-display use. A second broad oval is a suggestion; the child's actual art may be different. The original screen diagrams represent unmade 3D plans, not actual compound, a tested trial or unseen physical sides. Top suggests footprint; oblique suggests height. Names/relative positions/near edge are in the exact SVG description and expandable linear words, so colour is not needed.
The activity and short child prompts come first. Longer source/process/privacy explanation is expandable. Adult reads one control or description chunk at a time; no child reading test. Four choices can be completed by words/sign/AAC on paper or no-material routes, with exact A4 alternatives. Keep own form/space/meaning decisions real; a plan is useful before actual making but is not physical modelling evidence.
No outside script/font/image, network, storage, name field, photo, score or persistence. Native keyboard controls, visible focus, exact alternative, reset and reload operate locally. With JavaScript off, dead controls are hidden; a complete paper/directing route and static original example remain. Source graphics are distinct from held AC/AD; checks/key are not loaded here. Original text/art CC BY4.0, implementation Apache2.0, outside rights separate.
Reproduce the author browser audit
With a locally installed Node/Playwright runtime and Chromium available, from this pack run node digital/qa_browser.cjs. It is read-only by default. It checks 24 states × 1280, 390 and 320 (72 cases): actual shape type/positions/side-versus-footprint, exact words/ARIA, diagram bounds, option fit, overflow, all expandable text, keyboard/reset/reload, JavaScript-off paper route, page errors and outside requests. --capture explicitly writes previews. BrowserAct skill/runtime was inspected earlier in this author session; no configured API/browser was available, so installed local Playwright supplied the browser QA.
