v3: the docs follow deno doc's grain — the index page was a hand-kept list of some 250 links into deno doc's output layout (./api/main.ts/index.html), policed by mod.test.ts; deno doc has no module index of its own beyond all_symbols.html, which lists every module by path with its summary. mod.ts is now a prose overview of the three parts and their layers, linking that list once, and mod.test.ts is gone. Re-exporting everything from mod.ts, as deno doc's tutorial does for a library, was tried and doesn't fit: export * drops the 18 routers (default exports) and makes 17 names ambiguous, and deno 2.9 renders export * as namespaces with the root's module doc and nested ones empty, losing every module doc. A router's page showed one line: its endpoint list sat on the default symbol, whose summary was cut at the colon introducing it; the list is now the module doc of all 18 routers, and the router's JSDoc says so. 22 summaries ended in a colon (the routers, BandcampPlayer, migration 0016, useDumpListSync, usePlaylistListSync) and read cut short wherever deno doc shows a first paragraph alone; they end in a full stop, doc-lint.ts now fails on a colon summary, and the README states the rule. No behaviour changes; 204 backend tests pass.
