/* style.css — RAD 4 BMX, site vitrine.
   Palette dérivée du vrai logo (rouge #7e0000, blanc, gris) plutôt que la
   palette Admin/RAD4BIKE_PYTHON (bleu) - ce site public porte l'identité de
   marque réelle, pas celle des outils internes.
   --accent   : rouge de marque exact du logo, pour les surfaces pleines
                (boutons, badges) avec texte blanc dessus, comme sur le logo.
   --accent-2 : variante éclaircie du même rouge, pour le texte/liens/bordures
                sur fond sombre - le rouge de marque brut y serait illisible.
   Typo distincte du document de pricing interne : Barlow Condensed (titres,
   registre "vitesse/motorsport") + IBM Plex Sans/Mono (corps/données). */
