/* Settings as a pop-up sheet over the page, like OpenAI's (the Founder, 17 October 2026, 07:12; settings-sheet.js). A
   grouped grey ground; the title large with a round close at the top right; the plan on a card; rows on rounded cards,
   each with its icon, its word and a chevron, a hairline between rows. It rises from the bottom over the page, the page
   dimmed above it, never a page of its own (the Founder, 21 October 2026); on a computer it is a card in the middle. */
