/*
 * Theme tokens.
 *
 * Dark is the base because that is what this product has always been and what an unconfigured
 * install should keep looking like. Light arrives two ways: automatically for users whose OS
 * asks for it, and explicitly via [data-theme] when the user or the tenant has chosen.
 *
 * Cascade order matters and is relied on by ThemeService::cssVariables(), which injects a
 * tenant's accent using exactly this shape:
 *   1. :root                                  -> dark defaults
 *   2. @media light + :not([data-theme=dark]) -> follow the OS, unless overridden to dark
 *   3. [data-theme=light|dark]                -> an explicit choice always wins
 *
 * --on-accent is the foreground for anything sitting *on* the accent. It is a token rather than
 * a hardcoded near-black because a tenant's brand colour may be bright (yellow, lime), where
 * white text is unreadable and dark text is required. ThemeService computes it per accent.

   PulseGrid theme layer

   Adopts the PulseGrid template's visual language — cyan accent, deep navy
   panels, gradient cards, uppercase micro-labels, tinted status badges — on top
   of the existing token system, so per-tenant accent overrides keep working.

   ONE DELIBERATE DEPARTURE: the template sets type at 8–11px throughout. That is
   too small to read comfortably for a dashboard people watch all day, and it
   directly contradicts the readability pass done earlier. The look is adopted;
   the type scale is not. Micro-labels keep the uppercase + letter-spacing
   treatment that carries the style, at a legible size.
