SEO conventions

Marketing pages are server-rendered with semantic HTML and full meta tags.

Implemented

• <title> and <meta name="description"> per page
• OpenGraph + Twitter card meta on every page
• Canonical URL via app_url config
• application/ld+json SoftwareApplication block on / and /pricing
• Public sitemap.xml listing every public route plus generated docs
• robots.txt (in priv/static) referencing the sitemap

Performance hooks

• Tailwind v4 + esbuild minification (no tailwind.config.js).
• phx.digest adds long Cache-Control headers on hashed assets.
• A single app.css and app.js bundle keep the asset round trip count low.

Adding a new page

1. Add a route in router.ex.
2. Provide a controller action that assigns :page_title and :meta_description.
3. If it should appear in the sitemap, add the path to PageController.sitemap/2 (or, for docs, simply drop a new .md into the docs/ directory — Docs.list_pages/0 will pick it up at compile time).
