/*
 * Wariant nagłówka `mega` (chrome.json → "header": "mega"): pasek, mega-menu
 * „Usługi”, menu mobilne. Markup: parts/header/mega.php. Kolejkowany przez
 * agency_enqueue_chrome() (inc/assets.php) zaraz po base.css — tylko na
 * stronie, która ten wariant wybrała.
 *
 * Skąd: reguła po regule z sites/planmax/css/chrome.css (§1, §3–5 i części
 * nagłówkowe §10–11) — ten sam selektor, ten sam @media, ta sama kolejność
 * (spec chrome-wspolny §8). PlanMax po przeniesieniu wygląda piksel w
 * piksel jak przed (tooling/shots-diff.mjs --before, 60 widoków).
 *
 * Bez :where() — jedyny wyjątek od reguły base.css (spec D3,
 * docs/CONVENTIONS.md, Dodatek): selektory zachowują specyficzność źródła,
 * bo kaskada PlanMax była na niej zbudowana (np. `.s-hdr .s-hdr__cta:
 * focus-visible` bije `.s-hdr :focus-visible`). Wyzerowanie zmieniłoby
 * zwycięzców remisów wewnątrz wariantu. Skóra nadpisuje wariant selektorem
 * o specyficzności co najmniej równej — stoi później w kaskadzie.
 *
 * Pismo (font-*, line-height, letter-spacing, text-transform) zostaje w
 * skórze pod tym samym selektorem (sites/<klient>/css/chrome.css) — to
 * wartości marki (lint noBrandValues, spec D1).
 *
 * Kolor stoi w tokenie `--s-chrome-*` (nieprzezroczysty, theme.json strony →
 * custom.chrome, docs/tokens.md §2 „Tokeny chrome”), krycie w tym arkuszu:
 * color-mix(in srgb, var(--s-…) N%, transparent) — piksel w piksel to samo
 * co dawny zapis z kanałem alfa (docs/tokens.md §2 „Stopnie krycia”). CTA czyta istniejące
 * --s-accent / --s-ink-on-accent, pigułki i karta --s-radius-pill /
 * --s-radius-card. Geometria (odstępy, cienie, mniejsze promienie) i ruch
 * (czasy, krzywa cubic-bezier(0.22, 1, 0.36, 1)) to struktura wariantu —
 * literałem (spec D4).
 *
 * Stany przełącza js skóry (PlanMax: js/site.js) klasami `is-*`:
 *   .s-hdr.is-scrolled   y > 8 px          .s-hdr.is-mega      mega-menu otwarte
 *   .s-mega.is-open      panel mega-menu   .s-hdr__burger.is-open
 *   .s-mnav.is-open      menu mobilne      .s-mnav__sub.is-open (+ przycisk)
 *   html.is-menu-open    blokada przewijania
 * `html.is-js` stawia baza (agency_chrome_js_class(), inc/chrome.php).
 *
 * Odstępstwa od designu PlanMax (sites/planmax/handoff-map.json →
 * deviations): panele zamknięte mają `visibility: hidden` z opóźnieniem na
 * czas wygaszenia (bez niego ich linki byłyby osiągalne klawiszem Tab);
 * przycisk „Wyceń projekt” ma prostokąt 44 px wysokości (pigułkę rysuje
 * wewnętrzny span); widoczny `:focus-visible`.
