 Gallery pages are generated by `gather-gallery-pages` in `build-scripts/gulp/gallery.js`.

- A page id is the path under `src/pages/` without the extension, like `components/ha-button`.

 - A page may have only markdown, only a TypeScript demo, or both.
 - Markdown can contain YAML frontmatter with `title` and optional `subtitle`.
 - Markdown that contains only frontmatter contributes metadata without rendering a description block.
 - TypeScript demo modules are dynamically imported for side effects when the page is opened.
 - A demo module must define a custom element named `demo-${category}-${page}` with slashes replaced by hyphens, like `demo-components-ha-button` for `components/ha-button`.
- `ha-gallery.ts` renders that element with `dynamicElement()` based on the current page id.
