/* ==========================================================================
   SPRINT-THRU — MOBILE STYLESHEET
   --------------------------------------------------------------------------
   Scope   : screens BELOW 992px (Bootstrap 'lg' breakpoint)
   Purpose : adapts the desktop layout for phones/tablets. Contains ONLY
             mobile rules, so it can be safely loaded alongside the desktop
             stylesheet without affecting desktop rendering.

   LOAD ORDER (important — must be LAST):
     1. bootstrap.min.css
     2. font-awesome / aos.css
     3. Sprint_Thru_V5.css          (existing desktop base)
     4. sprint-thru-desktop.css     (desktop structural rules)
     5. sprint-thru-mobile.css      <-- THIS FILE
