   ONE FILE, because four pages carrying their own copy of a header is four
   headers that drift: the day one gets a menu entry, the others quietly do not.
   Page-specific rules stay in the page that owns them.

   Brand: the two hexes are the logo's own, reaching the screen exactly and at
   full opacity. A brand colour "adjusted for contrast" is a different brand

  /* FOUR ACCENTS, USED LIGHTLY. Julien, 31/08/2026: *« dans tout le site, j'aimerais
     bien qu'il y ait un petit peu plus de couleurs, même si c'est très léger et
     nuancé »*. So they colour small things — an icon chip, a figure, a card's edge,
     the rule down the side of a profile — and never a headline or a large surface.
     The first accent IS the brand blue, so the palette reads as a family rather than
     as four unrelated colours, and the logo's own hexes are untouched: a brand colour
     "adjusted to fit a palette" is a different brand colour. */
  /* Raised one notch on 31/08/2026 at Julien's word ("monte l'intensité d'un cran"):
     the tints are deeper and the rules darker, so the same restraint reads from a metre
     away instead of only up close. The ink stays exactly as it was — what changed is how
     much colour the surfaces carry, not the hues themselves. */
