// =============================================================================
// Styles specific to PlanningPage — colocated next to PlanningPage.tsx since
// nothing else uses these classes. Ported from the reviewed HTML mockup
// (see the plan file / PR description) onto the app's real design tokens —
// no light/dark duplication needed here, unlike the standalone mockup:
// every `var(--color-*)` below already resolves per-theme globally (see
// styles/_theme.scss).
// =============================================================================

// `.app-content` (AppLayout.scss) already stretches to the full viewport
// height (flex item of `.app-layout`, itself `min-height: 100vh` — the
// same stretch the sidebar relies on to pin its footer at the bottom).
// `.planning-page` just needs to fill that box and lay out as a column so
// `.planning-grid-wrapper` can grow to fill whatever's left under the
// header, instead of the grid being only as tall as its content.
