/* /read — the book corner's reader chrome (docs/prompts/reader.md).
   Typography IS the product (the Standard Ebooks lesson): serif, ~65ch measure,
   1.75 leading, generous margins. Three page themes — sepia (the reading default),
   paper, dark — while the CHROME (bars, drawers) stays brand navy in all of them.
   Long-form on navy is fatiguing; navy stays in the frame, not behind the words. */
