/* DESIGN SYSTEM (from design/mockup.html, approved by Anu 2026-09-24; reference/anti-slop-design.md)
   VOICE: a calm friend who is good with money. Plain words, never scolds, never sells.
   FONTS: display = Bricolage Grotesque (the number, headings) · body = Instrument Sans (UI).
          Tabular figures wherever a number can change.
   COLOR: fog bg · paper surface · ink navy text + hero number · marigold = the stretch + money in.
          No red anywhere (R11). Short states use weight and words, in ink.
   SHAPE: 4px base unit, radius cap 6px (pills only on the 3 actions), hairline borders, no shadows.
   LAYOUT PRIMITIVE: one column: the number, then the stretch, then the list.
   DO NOT: Inter/Roboto/Geist, indigo/violet/emerald, gradients, glass, glows, red, 3-card grids, streaks. */
