   Purpose : make every page behave correctly on mobile, tablet,
             laptop, desktop and large-desktop screens.
   Scope   : layout / structure only. No content, copy, fonts or
             images are changed — this file only patches spacing,
             wrapping and show/hide behaviour so existing content
             reflows correctly at every screen size.
   Load    : this file must be linked AFTER all other stylesheets
             (bootstrap.min.css, style.css, css.css, global.css …)
             so its rules can safely override the legacy CSS.

   1. PRIMARY NAVIGATION (the reported bug)
   -----------------------------------------------------------------
   Root cause: `.site-nav` is set to `white-space: nowrap` and its
   items use `display:inline-block`, so on phones the open mobile
   menu overflows sideways instead of stacking — only "Home / About
   Us / Programmes" stay on-screen and the rest of the links become
   unreachable. The submenus also only ever open on `:hover`, which
   doesn't exist on touch devices, so they'd be unusable even if the
   overflow were fixed.

   Fix: below the tablet breakpoint (767px) the menu is turned into
   a full-width, vertically stacked list, and submenus become
   tap-to-expand accordions (behaviour added in js/responsive-nav.js).
   Desktop/tablet hover behaviour above 767px is left completely
   untouched.
