/* ==========================================================================
   EUBS — Nubiss brand layer (navy + berry), light & dark, mobile-first shell
   --------------------------------------------------------------------------
   Vuexy hardcodes its primary colour (#7367f0) directly on component selectors
   (not via CSS variables) and uses !important on hover/active states, so this
   file retargets the real selectors, with !important where Vuexy does. Loaded
   after Vuexy's core/theme CSS so these rules win.

   Colour rules (brand):
   • Navy  #13348B  — the only structural colour: headings, marks, active nav,
     buttons, links, the dark substrate.
   • Berry #BD0068  — SIGNAL ONLY. One moment per surface (an unread dot, a
     "Now" pill, a "Your turn" chip, the preloader ring). Never borders, never
     backgrounds of areas, never buttons, never hover states.
   Dark mode: `html.dark-style` re-defines the same tokens (Vuexy's core-dark /
   theme-default-dark stylesheets are swapped in by templates/base.html).
