/* ARGADO - tarcica dębowa, sprzedaż hurtowa. Statyczna strona, bez buildu.
   Wersja 3 (2026-10-19): klasyczna strona firmowa z branży drzewnej.
   Paleta spróbkowana PIL-em ze zdjęć z placu (średnie z obszarów):
     --oak       #b28e62  drewno-15, nasłoneczniona płaszczyzna świeżych desek dębowych
     --oak-deep  #765d3e  drewno-27, pakiety desek w cieniu
     --oak-dark  #67543c  drewno-15, dolne deski pakietu w cieniu (hover)
     --bark      #2d271e  drewno-33, cień pod stosem w magazynie krytym (tekst, panele)
     --grey      #5d5956  drewno-02, zwietrzała ściana stosu (tekst wyciszony)
     --concrete  #b2a898  drewno-22, betonowe płyty placu (linie)
     --sand      #c7a87e  drewno-13, piaskowy plac (tło wierszy grup w tabeli)
     --sky       #7193bc  drewno-16, niebo nad rzędami (tylko ::selection)
     --bg        #f6f5f2  beton z drewno-22 rozjaśniony w 90 % do bieli (czyste, chłodne tło)
   Pisma: Zilla Slab (nagłówki, znak słowny) + Source Sans 3 (treść), oba z latin-ext.
   Kształty: radius 0 wszędzie (deski są prostokątne); jedyny wyjątek to otwór w tabliczce.
   Bloki @media dla wąskich ekranów stoją celowo NA KOŃCU pliku. */
