/* Deliberately minimal and unbranded.
   Jack is supplying visual direction (plan-23 §8.2); guessing at it now would
   only have to be undone. This is legible, responsive and theme-aware, and
   nothing more. Wide content scrolls inside its own box so the page body never
   scrolls sideways on a phone — error strings and code are long by nature. */
