/* =============================================================================
 * paper-trading-dashboard-v1 — global style polish (Agent C1).
 *
 * Goal: a consistent visual register across all eight pages without rewriting
 * the inline <style> blocks each page already ships. This stylesheet adds:
 *
 *   1. A single design-token layer (color, type scale, spacing, shadow,
 *      radius) usable from any page.
 *   2. Typography polish: serif display headings on h1/h2, clean sans body,
 *      tabular numerals on numeric cells.
 *   3. Table polish: zebra-striped rows, row hover, sticky-feel headers,
 *      monospace numerals — applied via `:is(table, .pt-table)` so both
 *      Inputs.table and any raw <table> in a markdown page pick it up.
 *   4. Card polish: subtle shadow + smoother hover on shared card classes
 *      already used on the pages (.pt-card, .pt-nav-tile, .sleeve-card,
 *      .pt-chart-wrap).
 *   5. Responsive baseline: container clamps and font scale ramps at the
 *      720px / 1024px breakpoints already used by the pages so we never
 *      introduce a NEW breakpoint that fights an existing one.
 *
 * NON-GOALS:
 *   - Do not redefine the per-page `<style>` blocks. They remain authoritative
 *     for page-specific grid layouts; this file is the shared baseline.
 *   - Do not touch sleeve colour assignments — those live in
 *     src/components/chart_helpers.js (SLEEVE_COLORS) and must not drift.
 *   - Do not change theme tokens that Observable Framework defines (var
 *     --theme-foreground etc) — we ADD a `--pt-*` token namespace alongside
 *     them so we never break the framework's light/dark toggle.
 *
 * BRIEF MAPPING (Agent C1 input contract):
 *   - #16a34a green   →  --pt-pos          (positive return / live badge)
 *   - #dc2626 red     →  --pt-neg          (negative return / failure)
 *   - #6b7280 neutral →  --pt-fg-muted     (secondary text, axis ticks)
 * ============================================================================= */
