/*
 * Design system — the entire visual language of the pi-tps lookalike.
 *
 * ONE stylesheet, no preprocessor. The theme is CSS variables on :root (light)
 * and .dark; every component references those variables, so re-skinning the whole
 * app is a two-line override (see THEME.md). Fonts (Geist/Geist Mono) and the
 * semantic tokens (accent/moss/amber/ember/violet) are declared at the top.
 *
 * LOAD-BEARING INVARIANT — never set overflow-x on html/body to hide a right-edge
 * overflow: it turns the body into a scroll container, breaks position:sticky on
 * the topbar, and collapses the layout sideways (hit + reverted live, screenshots
 * Unisic_*). Fix overflow by making grid children compress (min-width:0) and by
 * wrapping column tracks in minmax(0, 1fr) — see the responsive-grids section.
 *
 * Sections below, in order: tokens/theme, fonts+base, component recipes, layout,
 * pills, buttons, tables/badges/progress/deltas, forms, tooltips, scrollbars,
 * chart (axes + stacked bars), animation.

/* ---------- responsive grids (prevent right-edge cut-off) ----------
   Root cause of the cut-off: '1fr' columns with default min-width:auto mean a
   card cannot shrink below its content width, so wide content (tables, big
   cards) overflows the right edge of the frame.
   Fix: auto-fit + minmax(min(...)) so columns wrap to fit the container, and
   min-width:0 ONLY on grid children so they compress (their inner tables then
   scroll horizontally instead of pushing the page wider).
   IMPORTANT: never set overflow-x on html/body for this — it turns them into a
   scroll container, breaks position:sticky and collapses the layout sideways. */
