/* ===========================================================================
 * Genesis Mesh documentation theme overrides
 *
 * These values mirror the operator console palette in
 * genesis_mesh/na_service/operator_console/static/styles.css. Docs and
 * console must look like the same product; if the console palette changes,
 * update this file in the same commit.
 *
 * Operator console palette (verbatim):
 *
 *   Dark (default)              Light
 *   ------------------          ------------------
 *   --bg            #0a0d12     --bg            #f6f8fb
 *   --panel         #10161d     --panel         #ffffff
 *   --panel-strong  #151d26     --panel-strong  #eef3f8
 *   --line          #273241     --line          #d5dee8
 *   --text          #e8edf4     --text          #111827
 *   --muted         #a6b2c0     --muted         #5f6b7a
 *   --accent        #22c55e     --accent        #15803d   (identity green)
 *   --accent-2      #60a5fa     --accent-2      #2563eb   (interactive blue)
 *   --warn          #eab308     --warn          #a16207
 *   --danger        #f87171     --danger        #b42318
 *   --shadow        rgba(0,0,0,.18)   --shadow  rgba(16,24,32,.08)
 *
 * `--accent` (green) is reserved for identity surfaces only: the logo box,
 * section captions, the recognition graph. `--accent-2` (blue) carries
 * every interactive cue: links, code, hover, active state.
