Web Prototype Skill

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.

Workflow

Step 0 — Pre-flight (do this once before writing anything)

1. Read 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.
2. Read 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.
3. Read the active DESIGN.md (already injected into your system prompt). Map its colors to the six :root variables in the seed; don't introduce new tokens.

Step 1 — Copy the seed

Copy assets/template.html to the project root as index.html. Replace the six :root variables with the active design system's tokens. Replace the page <title> and the topnav brand.

Step 2 — Plan the section list

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.
