/* ══════════════════════════════════════════════════════════════════════════════
   FLEET PANEL (2026-10-06). The in-app view of the andy-monitor board.
   Lifted from the design mockup's `styles/fleet.css` block
   (shared/alon/Fleet_Monitor_InApp_Mockup.html, spec
   Fleet_Monitor_InApp_Design_Spec_2026-10-06.md), scoped under `.fleet`.

   Two colour rules carry the whole design, and both are easy to break:
   - The status ladder (crit / warn / notice / ok / unknown) deliberately has NO
     amber in it. Amber is --md-sys-color-human, and it marks ONLY something a
     person has to act on ("Needs you"). It never marks a status.
   - Green is a mark, never a surface and never text (the health.css contract).
     The hero takes its surface from the server's header_colour, its mark from
     the verdict.
   Solid shape = we have a reading, outline = we do not (see glyphs.js
   fleetMark). Colour is never the only carrier: every mark is also a shape and
   sits next to a word.

   The panel's geometry (width cap, gutter) is panel-layout.css's, via
   PANEL_LAYOUT.fleet = 'wide'. Nothing here sizes #panel-content.
