/* ============================================================================
   TSC Affordable Home Study Chrome - v1.0 - November 2026
   Header + footer for the cacourseprovider.com back-end pages, and the
   phone layout for those pages: register, login, student home, chapter view
   and payment. Stand-alone: references no other site's stylesheet.
   ----------------------------------------------------------------------------
   PART 1  header + footer ("airmail": stamp logo, red/ink airmail stripe,
           Archivo + Source Serif 4). Colours are the site's own, copied
           from affordablehomestudy.com styles.css :root (Nov 2026): ink
           #1B2A41 for structure, --act red #C0392B for action only.
   PART 2  phone layout for the platform pages (Foundation 5 base,
           register.css, the login page's inline styles, menu/chapter
           sheets). Layout only: no colours, fonts or button styles change.

   DESKTOP IS UNTOUCHED. Part 1 only styles .ahs-* elements. Every Part 2
   rule sits inside a max-width media query.

   ISOLATION
   - Part 1: every selector starts with .ahs-chrome and every class is
     ahs-*. Nothing targets a bare element or a class the platform uses
     (.row, .columns, .button, .label, .top-bar, .nav, .brand, .foot...).
     Foundation's globals (a colour, ul margins, small at 60%, b, h-tags)
     are reset inside the chrome only.
   - Part 2: every selector starts with ":root body". The platform links
     some sheets inside <body> (register.css) or after the header record,
     so they load AFTER this one; the prefix adds (0,1,1) so these rules
     still win at the same base specificity, whatever the load order.
