/* =============================================================================
 * kvtable.css - theme-aware refactor
 *
 * Was: hardcoded dark palette in :root (generic names like --bg0 leaking
 * into global scope). Now: --kv-* namespaced tokens defined per theme
 * class (.dark-theme / .light-theme, matching themes.css and themes_v2.css),
 * consuming the v2 tokens with hardcoded fallbacks so the component still
 * renders standalone. Companion edits in kvtable.js replace inline hex
 * colors with var() references so live values retheme with the page.
 *
 * DATA-DRIVEN COLORS NOT COVERED HERE: config JSON supplies per-group
 * header colors (config.color) and per-band alarm colors (row.range) -
 * those are applied inline by JS from data and may need light-tuned
 * values in the configs themselves.
 *
 * CONFIGURABLE COLUMNS (NEW): when a config supplies a "columns" array,
 * JS renders a .kv-colhdr header row and .kv-cell data cells whose width
 * and alignment are applied inline from the config. The rules below only
 * provide typography and layout defaults; sizing comes from the data.
 * ========================================================================== */
