/* B289 · The content pages, designed to be easy to use.
   1. The Lab and Scrubs hubs: newest first with Play or Read, start here, shelves you can play from, the Ledger, every note, follow.
   2. Note pages: a clear top, one way to listen, contents with progress, a strong ending.
   3. The Ledger: filter by status, scan by note.
   Blue #1559F5 is the only accent; Scrubs uses its violet. Rubik for the interface, Source Serif for CultureAI's words. */
