Produce a single, self-contained HTML prototype using the bundled seed and layout library — not by writing CSS from scratch. The seed already encodes good defaults (typography, spacing, accent budget). Your job is to compose it.

└── checklist.md ← P0/P1/P2 self-review
assets/template.html end-to-end — at minimum through the <style> block. The class inventory at the top of references/layouts.md lists every class that must be defined there; if one is missing, add it to <style> rather than re-defining it inline on every section.references/layouts.md so you know which section skeletons exist. Don't write a section type that isn't covered — pick the closest layout and adapt.:root variables in the seed; don't introduce new tokens.Choose one kebab-case artifact slug before composing the page. Use assets/template.html as the seed for the final artifact HTML.
Do not write a project-root HTML draft with file-write before emitting the final <artifact>. The live-artifact output is the canonical HTML file for this generation turn; an extra index.html, cast.html, or brief-derived draft can be stranded beside it as an orphan.
Replace the six :root variables with the active design system's tokens. Replace the page <title> and the topnav brand.
Pick layouts before writing copy. Default rhythms (from layouts.md):
| Page kind | Default rhythm |
|---|---|
| Landing | 1 hero → 3 features → 4 stats or 5 quote → custom split → 6 cta |
| Marketing / editorial | 1 hero-center → 7 log list → 6 cta |
| Pricing | 1 hero-center → 8 comparison table → 6 cta |
| Docs index | 1 hero-center → 7 log list (sections of docs) → 6 cta |
State the chosen list in one sentence to the user before writing — they can redirect cheaply now and not after 200 lines of HTML.
For each chosen layout, copy the <section> block from layouts.md into <main id="content"> of the artifact HTML. Replace bracketed [REPLACE] strings with real, specific copy from the user's brief. No filler — if a slot is empty, the section is the wrong choice; pick a different layout.
Run through references/checklist.md top to bottom. Every P0 item must pass before you move on. P1 items should pass; P2 are bonus.
Wrap the completed HTML in <artifact> tags using the artifact slug as the identifier. One sentence before describing what's there. Stop after </artifact>.
.ph-img class — never link to a stock photo CDN.data-od-id on every <section> so comment mode can target it.<artifact identifier="kebab-case-slug" type="text/html" title="Human Title">
<!doctype html>
<html>...</html>
</artifact>
Open Design derives the canonical HTML artifact from this identifier. Do not also write another root HTML file for the same generation turn.
One sentence before the artifact. Nothing after.
