/* ============================================================================
 * Space Company — Modern Design System : CELESTIAL OPERATIONS (M4)
 *
 * The orbital map, interstellar network and destination inspector that replace
 * the inherited solar-system navigation column.
 *
 * Scoping / safety
 * ----------------
 *  - Everything is scoped to html[data-ui="modern"][data-space="map"];
 *    `?ui=legacy` and `?space=legacy` fall back to the inherited panes.
 *  - The legacy navigation column is hidden ONLY while `#scCelestialCenter` is
 *    actually in the DOM (sibling combinator), so a failed build degrades to
 *    the legacy interface rather than to an empty pane.
 *  - No rule here references `.hidden`; the legacy visibility contract
 *    (docs/UI_DOM_CONTRACT.md) is untouched, as is `.tab-pane` display logic.
 *  - Every state carries a glyph and a word in the markup; colour is
 *    reinforcement, never the only cue.
 * ==========================================================================*/

/* The legacy nav column stays in the document — `activeSolarTab()`,
   `launchRocket()` and `explore()` all write to those rows, several without a
   null guard. We only take it out of view. */
