/* =============================================================================
   SIDEBAR NAV (nv-*) — classic desktop side menu for the trmc-mockup shell.
   GitLab-inspired behaviour: "Search or go to" palette, Pinned section,
   collapsible module groups, icon rail with flyouts, pinned footer.
   Rendered by assets/js/shell.js; replaces the legacy `.navbar.sidebar`.

   Three sidebar tones, each defined for BOTH themes:
     flush    — sidebar shares the page surface, hairline divider
     canvas   — header + sidebar become one darker chrome, content sits in an
                inset rounded panel (the GitLab "panels" layout)
     midnight — deep navy sidebar (stays navy in light theme too)
   Tone:   html[data-nv-tone]      Active style: html[data-nv-active="solid"]
   Labels: html[data-nv-labels="off"] hides section captions (separators stay)
