/* ============================================================================
   map-legend.css  —  the ONE stylesheet for every below-map legend across
   CrimeGrade, BestNeighborhood, and future sites.

   Loaded UP FRONT (before the map bundle) by each *_map_loader.php via
   ensureCss(MAP_LEGEND_CSS, 'map-legend'), so the legend is styled at first
   paint — long before the user clicks the teaser to load the live map. That
   is why this lives outside shared-map/src/ and is NOT part of any bundle:
   the bundle CSS only loads on the map-trigger click, which is too late.

   ── DO NOT fork this file or copy rules into a page. ──
   Pages express their few unique traits through the CSS variables below;
   everything structural (padding, fonts, toggle, icon, divider, clip-path,
   bar height, breakpoints) lives here and only here. See
   map-legend-guidelines.md. The defaults reproduce CrimeGrade "overall
   crime" — the gold standard — pixel-for-pixel.

   ── Variables a page MAY set on the .mlg-extlegend root (and nothing else) ──
     --mlg-grad-low / --mlg-grad-mid / --mlg-grad-high
                            3-stop gradient ends. Default = CG green/yellow/red.
                            Override the three under .mlg-cb-on for colorblind.
     --mlg-bar-gradient     full linear-gradient(...) string. Use ONLY for
                            multi-stop ramps (noise, politics) that cannot be a
                            single 3-stop. Replaces the bar fill without
                            touching .mlg-extlegend-bar.
     --mlg-bar-gradient-cb  colorblind variant of --mlg-bar-gradient.
     --mlg-end-low / --mlg-end-high
                            end-label colors (default: the low/high gradient
                            colors — required when --mlg-bar-gradient is used,
                            since the grad-* vars then no longer match the bar).
     --mlg-mark-size        in-bar mark font-size (default 18px = CG grades;
                            multi-character numeric marks usually want 14px).
     --mlg-cb-accent        "on"-state accent for switch + status text
                            (default: --mlg-grad-low).
     --mlg-seg-count        segment count (segmented mode; drives the narrow
                            fallback grid columns).

   Either one's default ~1em paragraph margins open a gap. The legend never holds
   a real paragraph, and the <p> before it carries only non-rendering nodes, so
   collapse both. (A <style> inside a display:none element still applies its
   rules, and the inline <script> already ran at parse time — so hiding the
