/* =====================================================================
   ZTech Campus — Classic Theme · Component Overrides
   ---------------------------------------------------------------------
   Loaded AFTER the layout's inline component CSS. Every rule is scoped
   under `body.theme-classic` so this file is a no-op for any other
   theme. The goal: take ZTech Campus's existing component patterns and
   re-paint them with classical institutional weight — serif display,
   gradient navy hero, milestone timelines, curved dividers, executive-
   card patterns adapted to the academic surfaces ZTC actually has.

   Surfaces touched:
     - Public marketing pages (homepage hero / stats / programmes / faculties / footer)
     - Admin/lecturer/student shells: chrome only (topbar, sidebar, headings)
       Inner work surfaces (tables, forms, lists) are deliberately untouched
       — operational density matters for grading, rosters, etc.

   The HomeController emits an inline gradient using var(--primary).

   background to use --gradient-brand (navy) instead, with a crimson
   accent ribbon below.

/* The inline hero in HomeController has these tells: a <section> with
   inline gradient on var(--primary) and color:#fff. We can't change
   the inline style, but we CAN over-paint it with a more specific selector
   using ::before. Better approach: target the <section> by direct child
   index + inline style attribute keyword. */
