/* ==========================================================================
   GEOPORTA — custom layer on top of Pico CSS (classless · sand)
   Load order: pico.classless.sand.min.css → style.css

   Two sections:
     1. BASE   — theme tokens (Pico variable overrides + local design tokens),
                 project-wide resets and element defaults
     2. CUSTOM — per-component styling. One class per component; everything
                 inside a component is reached with CSS nesting on semantic
                 elements, so the markup stays classless.

   Units: sizes are relative (rem / em / % / vw-vh clamps) so they ride
   Pico's responsive root-font scaling. Only hairline borders stay at 1px.

   Theming: colours are expressed as RGB-triplet tokens (--ink-rgb, etc.)
   and consumed with rgba(var(--token), a). The light values live in the
   light :root block; a prefers-color-scheme:dark block re-points only the
   atomic tokens, so every derived colour (borders, muted text, washes,
   Pico vars) flips automatically. Shadows use their own --shadow-rgb so
   they stay dark in both themes instead of inverting.
