/**
 * Employee Roster — shared responsive overlay
 * ---------------------------------------------------------------------------
 * Loaded in BOTH contexts, after the base stylesheet in each:
 *
 *   admin    admin/css/admin.css   (EMPR_Admin::assets)
 *   frontend public/css/app.css    (EMPR_Public::maybe_assets)
 *
 * Those two base files are a forked copy of one shared core and have drifted,
 * but they still share the wpr-* class names — so every rule here serves both.
 * They also each carry their own 720px/480px blocks; this file loads last, so
 * it can correct them at equal specificity without !important.
 *
 * Two hard rules for anything added here:
 *
 *   1. Only ever add rules INSIDE a media query. Desktop must stay untouched —
 *      that is what makes this overlay safe to layer over working CSS.
 *   2. Write each rule once. Selectors for classes that only exist in one of
 *      the two contexts (.wpr-avail-grid2 is admin-only, .wpr-avail-row is
 *      frontend-only) are simply inert in the other, which is fine.
 *
 * Tiers: 1440/1200/1024 laptop→tablet · 768 large phone · 600 table card-stack
 *        · 480 phone.
 *
 * The laptop/tablet tiers below are floored at min-width:769px on purpose. This
 * file loads last, so an unfloored max-width:1440px rule would also win at
 * 400px and silently undo the tighter phone sizing both base files already set
 * in their own 720px/600px blocks.
 *
 * NOTE: this file must not live under the top-level assets/ directory — the
 * packaging step removes that folder, so it would 404 in the shipped plugin.

/* ══════════════════ SHIFT CALENDAR — LAPTOP (769–1440px) ══════════════════ */
/*
 * Week view is the widest thing the plugin renders: the member column plus one
 * column per day. At the base minimums that is 176 + 7×140 = 1156px, which is
 * wider than the content area of a 1280 or 1366 laptop once the WP admin menu
 * is expanded — so .wpr-roster-wrap starts scrolling sideways on the most
 * common screen the roster is actually used on.
 *
 * Rather than step the minimums down per breakpoint, tie them to the viewport
 * so the fit is continuous. The 380px reserve (admin menu + page padding +
 * member column) is deliberately generous, and costs nothing when it
 * over-reserves: .wpr-roster-table is width:100%, so whatever room is left over
 * is redistributed across the columns anyway. min-width here is only a floor.
