   AltProductionHosting Panel — app.css
   Path: /opt/aph/panel/assets/css/app.css

   DESIGN INTENT
   -------------
   This stylesheet is the permanent visual foundation for the panel.

   Principles:
   - Human-first: readable, calm, high contrast without being blinding.
   - Operator-first: status badges, alerts, and actions are unmistakable.
   - Modular: modules can add their own CSS without breaking global layout.
   - Minimal dependency: no frameworks required.
   - Safe defaults: if a module ships no CSS, it still looks coherent.

   COLOR SYSTEM
   ------------
   We use a dark control-room theme:
   - Background: deep navy
   - Surfaces: translucent glass panels
   - Borders: subtle white
   - Text: high contrast
   - Status colors: green/amber/red

   IMPORTANT
   ---------
   - Do not hardcode colors in module pages. Use the CSS variables below.
   - Modules may ship: /modules/<module>/assets/css/module.css
     which is loaded later (optional) and should prefer variables.
