/* Taikyokai SDF Events - Frontend
 *
 * Breakpoints used by this stylesheet and the companion frontend.js
 * (keep these four values in sync if adjusted — they express distinct
 *  design intents, not mere duplicates):
 *    720px — card grid: stack vs. horizontal layout for list items
 *    768px — SP tab switch + calendar icon density (mobile vs desktop)
 *   1024px — host-theme content column widening ("wide wrap")
 *    750px — TCD theme SP FV guard (site-tweaks.php)
 *
 * Service palettes come in two tiers. "Light" is the badge color
 * (`--tkek-army`, `--tkek-navy-svc`, `--tkek-air`); "dark" is used by
 * calendar service underlines, mascot gradients, and the per-service
 * shield icons. The dark palette was previously hardcoded in three JS
 * places — audit A-1 (v1.2.4) consolidated them to the three custom
 * properties below; frontend.js reads these at init via readPalette().

/**
 * IMPORTANT — no breakout / no transform on .tkek-wrap.
 *
 * Earlier versions used `position: relative; left: 50%; transform: translateX(-50%)`
 * to break out of the host theme's content column to force a 1200px-wide
 * layout. That approach had two problems on the live TCD theme:
 *
 *   1. The theme's content column is intentionally left-biased (the
 *      right ~30% of the viewport is reserved for a decorative image),
 *      so centering on the parent column produced a visibly left-shifted
 *      plugin block that also overlapped the decorative area.
 *
 *   2. `transform` on an ancestor turns `position: fixed` descendants
 *      into position-relative-to-that-ancestor, which broke the event
 *      detail modal — it scrolled out of view instead of staying pinned
 *      to the viewport.
 *
 * We now respect the host theme's content column: the plugin just fills
 * its natural parent width. At the wide viewport it's still up to 1200px
 * via .tkek-wrap's max-width. No transform, no negative margins.

/**
 * Host-theme column widening on pages that contain the [sdf_events_view]
 * shortcode. The TCD muum_tcd085 theme constrains #main_col to 740px at PC
 * and reserves ~40px right-gutter for a sidebar. That leaves a wide empty
 * strip on the right of the plugin's content column.
 *
 * When the plugin detects a shortcode on the page, it adds body.tkek-fullwide
 * via a body_class filter (see includes/frontend.php -> tkek_body_class).
 * We then widen #main_col to 100%/max-1200px and hide #side_col, ONLY on
 * pages that opt in via that body class, ONLY at >=1024px. Narrow viewports
 * continue to use the theme's responsive behavior (full-width with padding).
 *
 * Note: we widen the parent container (#main_col), NOT the .tkek-wrap via a
 * transform/negative-margin breakout. The old breakout approach caused
 *   (a) a left-shifted plugin block on a layout biased toward a decorative
 *       right area, and
 *   (b) position:fixed descendants (the event detail modal) to be trapped
 *       inside the transformed ancestor.
 * Widening the parent avoids both issues.

 * (see frontend.js `renderCalendar`). FullCalendar's built-in list layout
 * is already compact and vertical, but a few tweaks keep it on-brand and
 * maximize the number of events visible without scrolling:
 *   - tighter toolbar (smaller padding, font-size) and a short "今日" label
 *   - smaller row padding on list events
 *   - service-colored dot swapped in for FC's default colored square
 *   - compact title/time typography
 *
 * Kept inside the existing SP media query block above, but scoped to the
 * listMonth view only (`.fc-list`) so dayGridMonth on SP is unaffected when
 * the user switches views via the toolbar button. */
