A YouTube search is `?yt=<term>` (+ `ytn` for a non-default count), so a reload, a link or Back/Forward reopens it. It runs by itself only where it costs no quota: the free page scrape, a search asked for in this document, or results still cached. An API search reopened any other way shows its term and waits for "Search YouTube again". Home's time budget is `hb`; the question's draw stays on the history entry. An e2e spec opens every page's bookmark in a fresh browser context; CLAUDE.md and docs/development.md name the module URL codec as the place for view state.
