/* DelveTalk: the Field Notebook by day, the Night Herbarium and Ledger by night.
   Day: ruled paper with a margin, iron-gall ink, pressed-flower accents, a botanical mark beside every door. Night: slate, bone, the garden's colours.
   Receipts are stamped tickets: the stamp's icon and word are in the markup, so a screen reader and the plain-text view keep them; colour only repeats them.
   A refusal is set as large as the card body: the moment a spell fails is when the page must be easiest to read.
   The palette is the two token blocks below and nothing else; site/style.css carries the same tokens, and tests/test_theme.py
   checks every text-on-surface pair in both for WCAG AA. Change a colour here and in site/style.css, then run that test. */
