/* plan.css — Plan-area view styles (ported from ala-scheduler/css/layout.css).
 *
 * Every rule that targets content living inside #area-plan is scoped under
 * `.area-plan` so the planning grids never leak into the Day area's unscoped
 * grid.css (a `.area-plan`-scoped rule at specificity ≥0,1,1 beats Day's 0,1,0).
 *
 * Three families are intentionally UNSCOPED because their markup mounts outside
 * #area-plan:
 *   • the conflict modal (slotpanel appends it to document.body)
 *   • the setup modal (#setup-modal sits in #screen-app, not #area-plan)
 *   • the week-zoom slider (lives in #chrome-plan header chrome)
 *
 * Shared chrome already lives in layout.css (#term-select, #breadcrumb/.bc-*,
 * .session-stats), base.css (.filter-chip) and students.css (.modal-* base,
 * .plan-modal-dialog, .plan-quill, .form-group, .status-badge) — not redefined.
