/* ===== KwK Kursvielfalt Shortcode — CSS v9 (2026-06-04) =====
   v1 (2026-05-06): grid + popup, lifted from /kurstermine/.
   prior (2026-05-24): added filter row, label badges, price tag, empty-state.
   v2 (2026-06-02): filter-bar redesign — segmented dark/glass pills, copper
                    filled active state (no cheap glow), grouped (taste pills |
                    divider | price pills) with a leading label, edge-faded
                    horizontal scroll-snap on mobile. Filename-versioned to
                    bypass the Hummingbird ?ver= cache strip (see febas-hosting).
   v3 (2026-06-03): active filter pill — removed colored copper glow box-shadow,
                    now a minimal neutral rgba(0,0,0,.18) lift only. Saisonkurs
                    badge moved off gold/orange onto the copper gradient.
   v4 (2026-06-03): (1) Veggie label split into two distinct visuals —
                    .kwk-klabel-veggie stays FILLED solid green ("Vegetarisch",
                    = the course IS vegetarian); new .kwk-klabel-veggie-option is
                    an OUTLINE chip (dark translucent bg, green border + green
                    text, outline leaf) for "Veggie-Variante möglich" (= an
                    OPTION, not a property). (2) Filter bar now holds 8 pills —
                    it wraps to 2 centred rows on desktop (flex-wrap) and keeps
                    the horizontal scroll on mobile; a "Preis" sub-label leads
                    the price group. Filename-bumped v3->v4.
   v5 (2026-06-03): MULTI-SELECT filter (JS rewrite v4->v5.js). Several pills
                    can now be active at once — the .kwk-kfilter-active copper
                    fill already renders correctly for any number of active
                    pills, so the per-pill colouring is unchanged. The
                    "Alle Kurse" reset pill carries the same active fill and
                    auto-highlights when nothing else is selected. Filename-
                    bumped v4->v5 in lockstep with the JS so the Hummingbird
                    cache serves the matching asset set.
   v6 (2026-06-04): TWO-COLUMN filter bar (Filtern | divider | Preis), reset
                    centred below. Superseded same day by v7 (JK wanted rows).
   v7 (2026-06-04): TWO STACKED ROWS instead of two columns. Each row is a
                    horizontal "label + pills" line: row 1 = "Filtern" + taste
                    pills, row 2 = "Preis" + the 5 price pills. The two rows are
                    stacked vertically and parted by a subtle hairline; the labels
                    share one fixed-width column so "Filtern"/"Preis" line up
                    directly under each other and the pill groups start at the same
                    x-offset. Pills wrap within their own row on narrow widths.
                    "Alle Kurse" reset stays centred underneath. Mobile keeps the
                    same two-row idea: the label sits above its (wrapping) pills.
                    Pure CSS relayout — markup regrouped (.kwk-kfilter-col ->
                    .kwk-kfilter-row); pill classes + data-attrs unchanged, v5 JS
                    untouched. Filename-bumped v6.css -> v7.css.
   v8 (2026-06-04): PER-ROW "Alle" reset pill. The single central "Alle Kurse"
                    reset pill (and its .kwk-kursvielfalt-resetrow wrapper) is
                    removed; instead each row carries one pre-selected reset pill
                    at its left ("Alle Kurse" in the taste row, "Alle Preise" in
                    the price row) styled with .kwk-kfilter-allrow — same pill
                    look, copper when active, set slightly apart from the rest of
                    the row with extra trailing space. JS rewrite v5->v6 (per-group
                    reset + per-group auto-on). Filename-bumped v7.css -> v8.css.
   v9 (2026-06-04): ROW-1 CATEGORY FILTERS. Row 1 grows from 3 to 6 pills
                    (+ "Grillkurse" / "Fisch & Meeresfrüchte" / "Cocktails &
                    Drinks"). To keep the now-wider row 1 from wrapping into a
                    tall, ragged stack, the filter wrap max-width is widened
                    (720 -> 880px) so it lays out as ~2 tidy lines on desktop;
                    the price row keeps its 6 pills on (mostly) one line. Pill
                    look, copper active state, hairline + per-row reset all
                    unchanged. JS rewrite v6->v7 (OR row-1 logic + category
                    predicate + Coming-Soon-under-row-1 rule). Filename-bumped
                    v8.css -> v9.css (in lockstep with v7.js for the cache strip).
   Theme variables (--kwk-radius, --kwk-border, --kwk-gold-border, --kwk-dark2,
   --kwk-text-dim, --kwk-gold, --kwk-gold-light) come from the page theme; the
