/* PaceBand
   Mobile first: one column, large touch targets, actions pinned to the bottom of the screen.
   From 54rem up: settings panel on the left, a timing sheet on the right. The sheet switches to
   stacked cards when its own column is too narrow (app.js toggles .stacked), not just
   when the viewport is.
   Look: condensed race-signage numerals, bib-orange accent, cool slate neutrals. */
