/* ==========================================================================
   AERONEX UI · shared stylesheet (v1.0, 2026-10-16)
   The look of the Aeronex BBC dealer portal (bbc.aeronex.ae), written for the
   class names of the DOCK 3 BOQ Design Tool (tools-dock3.aeronex.ae).

   HOW TO USE
   - Replace BOTH  css/style.css  and  css/brand.css  with this one file:
       <link rel="stylesheet" href="css/aeronex-ui.css?v=20261016">
     (it covers every class those two files define, plus the page, admin,
     login and report screens). If you must keep style.css for now, load this
     file AFTER it; it still works, but delete brand.css.
   - Keep Font Awesome for the moment. Decorative icons (titles, labels, quick
     links, emoji in cards) are hidden here; functional ones (arrows, close,
     upload) stay small and grey. Long term, swap Font Awesome for thin outline
     icons (e.g. Lucide, 1.75px stroke, 16px).
   Application adaptation (2026-10-17): conflicting summary inline styles
   removed; mobile Feedback is inside navigation; short viewports use flow.
   Original, unmodified package is archived under docs/design/aeronex-ui-v1/.

   THE RULES THAT MAKE IT LOOK LIKE THE BBC
   1. White paper, ink text, ONE teal accent. Teal only for the main action,
      the selected item, focus and progress. Never decoration.
   2. Dark "stage" (#04080A) only for the slim top strip, login and footer-like
      areas. Working areas (forms, summary, tables) stay light.
   3. One font (Inter), three weights (400 / 500 / 600), a fixed size scale.
   4. Pills for buttons, 1px hairlines for cards and inputs, no heavy shadows.
   5. Status = small pill with a dot + a word. No uppercase eyebrows over titles.
