/* Webinars index design layer.
 *
 * The presentation layer for Components/Pages/WebinarsPage.razor. Global CSS,
 * linked from App.razor — it was Blazor-scoped until the stylesheets were
 * consolidated under wwwroot/css. The same two rules the sibling sheets call
 * out apply:
 *
 * 1. Nothing confines these rules to this page any more, so every selector is
 *    qw- prefixed or a descendant of one.
 * 2. @keyframes names are global too. Hence the qw- prefix on
 *    every one, so they cannot collide with the compiled Tailwind bundle or with
 *    Home's qh-, pricing's qp-, the blog's qb-/qd-, the help centre's qc-, the
 *    HR laws centre's ql- or the video pages' qv-/qvd- animations.
 *
 * These rules are unlayered and Tailwind v4's utilities live inside @layer, so
 * they win regardless of specificity. Keep every selector class-based and
 * prefixed.
 *
 * Palette is the logo ramp shared with the pricing, blog, help-centre and video
 * pages: #a22dea (magenta-violet) → #7b5ee5 → #5b5de2 (indigo-blue), with
 * #4f46e5 → #7c3aed as the primary. No hue from outside that ramp appears here.
 *
 * Layout: hero → one uniform grid of webinar cards, or a single centred empty
 * state. The empty state is the branch that actually ships today (no events are
 * published), so it is treated as a first-class panel rather than as loose copy.
