/* ============================================================================
 * Space Company — Modern Design System : RESOURCE OPERATIONS DASHBOARD (M2)
 *
 * The responsive resource-card system from docs/VISUAL_DIRECTION.md ("Resource
 * cards"), replacing the legacy fixed-380px, 4-column resource TABLE.
 *
 * Scoping / safety
 * ----------------
 *  - Everything is scoped to html[data-ui="modern"][data-resources="cards"];
 *    `?ui=legacy` and `?resources=legacy` fall back to the legacy table.
 *  - The legacy column is hidden ONLY when the dashboard is actually in the DOM
 *    (`#scResourceDashboard ~ ...`). If the dashboard script fails to build, the
 *    legacy list stays visible — the fallback is structural, not a promise.
 *  - No rule here references `.hidden`; the legacy visibility contract
 *    (docs/UI_DOM_CONTRACT.md) is untouched, as is `.tab-pane` display logic.
 * ==========================================================================*/
