  /* ---------- Design tokens ----------
     Colour: a near-black ground (never pure #000) plus four accent hues,
     one per dossier project (D01 PhoneStock / D02 Phoenix Chicha /
     D03 Notre Budget / D04 VendreMaVoiture). The accent is a filing system,
     not decoration — it identifies which project you're looking at.
     Type: Fraunces (display, self-hosted) + Archivo (body) + system
     monospace (technical/data labels — a deliberate register, not a
     fallback). Scale: 4px spacing rhythm, a defined type scale, three
     radius tiers. Every value below traces back to one of these tokens. */
