/* --------------------------------------------------------------------------
   YSF DASHBOARD — project layer.

   Loaded AFTER assets/brand.css (vendored, never edited) and BEFORE the page
   markup. Drives three things:

     1. The slot override.  The pack's GUIDE §2 documents `--brand-accent` as
        the single point of variation, but the vendored brand.css does not
        alias every accent role to it (the shadow tokens are literal).  This
        file performs the aliasing so changing `--brand-accent` cascades to
        every accent role.  Currently set to phosphor cyan to match the morse
        trainer at 4e9kkz-morse.duckdns.org — same callsign, same operator,
        same family.

     2. Density override.  The pack's spacing scale (2/4/8/12/16/24/32/40/48/64)
        is ~50% too loose for a single 1080p ham-shack monitor.  Re-scaled to
        75% for cards, sections, and headers, but the typography, radius,
        shadow, and motion scales are unchanged.

     3. Project-level components the pack does not ship.  Specifically:
          - .activity-table  molecule (Last Heard, Linked Gateways)
          - .connect-panel   the endpoint panel
          - .on-air          active-transmission callout
          - .system-strip    one-row operator telemetry
          - .stat            label/value pair inside the system strip
          - .tag--ok/warn/err/info  status variants
          - [data-fresh]     row-level "new since last refresh" affordance
          - .icon            inline-SVG sizing + currentColor stroke contract
        All of these resolve only through pack tokens — no raw hex, no
        arbitrary px outside the pack's scale, no border-radius > 0 except
        2px (inputs) and 9999px (pills).

   Hierarchy contract (2026-11-04): the page is weighted by what a visitor
   came for, not by what the server knows.

     endpoint / live callsign   --text-xl (32px)   ← the reason to be here
     identity                    --text-lg (24px)
     operator telemetry          --text-sm (14px)  ← demoted to one strip
     labels / chrome             --text-xs (12px)

   a11y: respects prefers-reduced-motion and forced-colors throughout.
