/* ── gen_panel.css ──────────────────────────────────────────────────
   Modern control-panel layout for the generator pages (June 2026).
   Replaces the 2017 <br>/absolute-positioning layout INSIDE the panels;
   panel placement on the page and all input ids/handlers are unchanged.
   Scoped per panel root (#ctrlPanel = SymbolGen, #params = HMV) so other
   pages are unaffected. Colors follow gen_skin.css (deep space nova). */
