/* Public website, redesigned 2026-10-06 (decision 96) in the manner of a
   Material 3 landing page: one warm tonal palette around the brand rose,
   large display type, flat tonal containers instead of shadows, pill
   buttons, generous white space, and motion that is CSS only (the app on a
   phone swiping by itself, a changing headline word, a ticker, cards that
   rise as they scroll in). System fonts only: nothing is loaded from
   another site. Earlier decisions 72, 73, 76, 87 and 94 are superseded here. */
