/* KitRoost design system — vanilla, zero deps
   Layer 1: base + tool pages. Layer 2: sticky chips, share, back-to-top, print.
   Layer 3: home page (index) layout. Tool-page rules are unchanged by Layer 3.
   v2 (2026-11): serif display + sans body; fields, outputs and related links are wrapping flex
   rows with a floor width per item, so a long word cannot blow out a column, a short row fills
   its line instead of leaving a hole, and every tile on a line shares one height; card grids are
   width-driven columns of equal size; output tiles put the label above a shared baseline; chrome
   carries no pill-and-emoji decoration. Class names are unchanged; app.js needs none. */
