/* components.css — shared visual primitives.
 *
 * Anything that's used on 3+ pages and would otherwise be re-invented in
 * each page's inline <style> block belongs here. Canonical list:
 *
 *   - .nv-toast*         — ephemeral feedback, paired with js/toast.js
 *   - .nv-empty*         — empty states for zero-data list views
 *   - .nv-skel--*        — content-shaped skeletons (feed row, market row,
 *                          source row, prediction card, table row)
 *   - .skip-link         — keyboard-user "skip to content" anchor
 *
 * All selectors are monochrome by design — colours come from tokens.css
 * so a theme flip updates every component without a per-component
 * override. If a design system change needs a coloured accent, add it
 * via a CSS variable, not a hard-coded hex.
