/* Volume Monitor - shared site layout + reusable components (loaded after app.css).
   Uses app.css variables only (--bg --panel --panel2 --hover --line --line2 --text --muted --dim
   --up --up-bg --down --down-bg --warn --conf ...), so dark/light themes just work.

   Layout (base.html):  .top > .brand(.brand-name) + .sitenav(a[aria-current=page]) + .actions
                        .footnav in the footer
   Page heading:        <section class="pagehead"><h1>..</h1><p class="lede">..</p><p class="meta">..</p></section>
   Page body:           <main class="page"> .. </main>  (16px gutters on phones, 20px on desktop, max 1400px)
                        .grid2 = two columns >= 1000px (use .span2 to span both), .section h2 = section title
   KPI cards:           .stat-grid > .stat > .stat-label + .stat-value + .stat-sub (+ .split > i.l / i.s bar)
                        .tag (small pill), .tag.warn for "partial" etc.
   Panels:              .panel > .panel-h(h2 + .muted note) + content   (card with header row)
   Data tables:         .tablescroll > table.dtable  (sticky header, th/td.r = right-aligned numbers,
                        td.up / td.down colors, th[data-sort] clickable, .coinlink for /coin/<BASE> links)
   Segmented control:   app.css .fgroup.seg > button.tg ; active = .on or aria-pressed="true"
   Chart container:     .chart (relative; put an <svg> inside) + .chart-tip tooltip + .legend > .key.l/.key.s
   History chart:       {% include "partials/series_chart.html" with metric="oi" base=base title=".." %} -> .panel.sc
                        (several series in one chart: layers='[...]' -> .sc-legend; wide="1" -> .sc-wide in .sc-grid)
   Referral CTAs:       {% include "partials/signup_cta.html" with venue="bybit"|"hyperliquid" page="<id>" %} -> .su card;
                        .su-row = cards side by side, .su-strip = titled strip (.su-strip-h), .card.su-card = stacked list,
                        .su-mini = tiny inline "sign up" link (table rows). Footer disclosure: .disclose
   Misc:                .hide-sm (hidden <= 640px), .note (small muted paragraph), .num (tabular mono numbers), .faq from app.css
