/* admin.css - v1.3 - Restore Stream Tiles + Bigger Donut
CHANGELOG (v1.2 -> v1.3): Re-added .metric-grid/.metric-tile - removing
them in v1.2 (thinking metrics.html was the only user) broke Stream
Metrics, which still uses them for its Live/Peak/Average tiles. Donut
chart bumped 170px -> 210px and given a left margin per request.
CHANGELOG (v1.1 -> v1.2):
  - Nav rebuilt from a fixed 200px sidebar into a header (icon + title)
    and an underline-style horizontal tab bar, matching PAP-KB's Knowledge
    Dashboard. Same dark background / red active-accent / green highlight
    colors as before - layout changed, palette didn't.
  - Actually fixed mobile this time: previous v1.1 mobile rules were
    correct in the CSS file but Cloudflare was serving browsers a cached
    pre-mobile admin.css for up to 4 hours (no version on the URL) - see
    base.html's changelog. The tab bar is now also just inherently more
    mobile-friendly than a sidebar was (scrolls horizontally instead of
    squeezing page content).
  - Added .stat-row/.stat (plain, unboxed KPI numbers - PAP-KB doesn't box
    its metric tiles) and .two-col/.donut-chart-wrap for the new Metrics
    page layout (chart + gaps table side by side, like PAP-KB's Search
    Outcomes / Zero-Result Searches split).
  - Dropped the old boxed .metric-grid/.metric-tile - metrics.html no
    longer uses them (kept .card for other pages that still want a boxed
    section, e.g. Content Viewer, Article Editor).
