Add site search to my {{tech_stack}} project. Read the existing code first, list the public pages and content types that search should cover, and show me a short plan before changing files. Pick the approach by size and tell me why: a prebuilt static index for a few hundred pages or fewer, the database's own full-text search for content stored there, or a hosted search service only if we need typo tolerance at scale. Experience: - A search box in the header that the slash key opens, and a full-screen search view on phones - Results as you type after two characters, with a short debounce - Each result shows the title, a snippet with the matched words highlighted, and its section or type - A results page with the query in the URL, so searches can be shared and bookmarked - A helpful no-results state with suggestions and popular links Rules: - Only published content, and never anything the visitor isn't allowed to see - Keyboard and screen reader support using the combobox pattern: arrow keys, Enter, Escape and an announced result count, meeting WCAG 2.2 AA - Log searches that return nothing, without personal data, so I know what content to add When you're done, list the files changed, how the index stays up to date, and anything you assumed.
