description	Write, add, or update a documentation page in this docs-kit site. Use when asked to document a feature, endpoint, class, or workflow, or to add or edit a page under app/views/docs/pages/. Scaffolds with `rails g docs_kit:page`, writes Markdown-first content, and runs the verification gates.

Write a docs page

This is a docs-kit site (Site). Every page is a DocsUI::Page subclass; the shell, sidebar, "On this page" TOC, search, and the .md twin all come free. Your job is to scaffold a page and write its #content — never hand-write HTML or daisyUI markup.

The full authoring contract is in the repo's AGENTS.md. This is the recipe.

1. Gather the subject

Identify exactly what to document (the code, endpoint, or workflow) and where it belongs in the sidebar (the --group). Read the relevant source first — do not invent behavior. If the subject is an HTTP endpoint, prefer DocsUI::RequestExample / DocsUI::FieldTable; if it's a Ruby API, prefer DocsUI::PropTable.

2. Scaffold (one command)

rails g docs_kit:page "Page Title" --group=Guide

This writes app/views/docs/pages/<slug>.rb and injects the required page "…" registry line into app/models/doc.rb. Overrides: --slug, --view, --eyebrow, --registry. If it reports a legacy entries [...] registry, add the printed line by hand.

3. Write #content — Markdown first

• Set title, eyebrow, and a one-sentence lead.
• One DocsUI::Section("…") per part of the page — Sections own structure and the TOC. Never use a Markdown ## for page structure.
• Prose is md <<~'MD' … MD — a single-quoted heredoc (no escaping, no interpolation; Phlex escapes author text). Markdown ### is only for sub-headings inside a Section.
• Reference material: DocsUI::PropTable, DocsUI::FieldTable, DocsUI::RequestExample, DocsUI::Code(source, filename:), DocsUI::Callout(:note | :tip | :warning).

class Views::Docs::Pages::PageTitle < DocsUI::Page
  title "Page Title"
  eyebrow "Guide"

  def lead = "One sentence describing the page."

  def content
    DocsUI::Section("Overview", description: "What this covers.") do
      md <<~'MD'
        Prose as **Markdown**. Fenced ```ruby``` blocks highlight; `inline code`,
        lists, links, and GFM tables all render styled.
      MD
    end
  end
end

4. Self-review against the checklist

• The page "…" registry line exists (the generator adds it).
• Structure is DocsUI::Sections, not Markdown ## headings.
• Prose uses md <<~'MD' (single-quoted); no html_safe, no raw.
• No hand-written HTML/daisyUI markup, no per-feature Stimulus controller.
• Reads correctly with JavaScript off (the server renders it fully).
• Any new theme is in both c.themes and the Tailwind @plugin block.
• No inline rubocop:disable to force layout.

5. Run the gates

bundle exec rspec && bundle exec rubocop
bun run build:css   # only if you added classes the CSS must scan

Then render locally (bin/dev, open /docs/<slug>) and confirm it reads well. For depth on any idiom, read the live Authoring pages doc.
