/* SimovaTrack MQTT History — dashboard styles.
   Design tokens defined once on :root (light), overridden under prefers-color-scheme:
   dark. This is a LAN-only admin tool with no explicit theme toggle, so it just follows
   the OS setting.

   2026-08-18: hex values swapped to match simova-track-idf6/frontend/shared.css's
   palette exactly (--c-bg/--c-fg/--c-card-bg/--c-success-fg/etc.) — same device-UI
   family as the Snapshot panel's card system ported from that file. Variable *names*
   stay this app's own (--bg/--text/--surface/…, used throughout app.js's coloredText()/
   getSettings() already) — only the colors they resolve to changed. --accent-dim has no
   equivalent token over there (that repo doesn't have a tinted-accent background), kept
   as this app's own derived tint. */

   tables follow the app's light/dark theme instead of Tabulator's bundled light theme.
   Selectors here deliberately mirror the nesting depth of the tabulator.css rule they're
   overriding (e.g. ".tabulator .tabulator-header .tabulator-col") — Tabulator's own CSS
   sets several of these backgrounds at 3-class specificity, so a shallower override here
   loses even with correct load order. Both renderFleet()'s fleet table and loadLog()'s

/* Snapshot panel — collapsible cards of stat tiles, one card per data group

   .status-item (same collapsible-card + tile-grid system that repo's own
   device dashboard uses for its "Device Status"/"Live API Data" cards) —
   colors stay on *this* app's own --surface/--border/etc. tokens rather than
   forking a second palette. "snap-" prefix keeps these distinct from this
   app's existing .panel (the bigger Snapshot/Command/Chart sections these
   cards nest inside). 2026-08-18: replaces the old flat .kv-groups grid,
   which gave every group an equal-width column regardless of row count — a
   3-row group (Health) and a 12-row one (Device) ended up visually
   mismatched. Collapsing groups you don't need open fixes that directly.

   Chosen from a set of prototyped alternatives (masonry columns, dense flat
   table) — Italo's call: this dashboard already borrows can_simulator.html's
   AT-console conventions, and pulling in its collapsible-card system too
   keeps the two device UIs feeling like one family. */
