/**
 * Mobile-first responsive overrides for the LMS.
 *
 * The vendored Alina template (style.css / responsive.css) already handles
 * most breakpoint behavior — this file only adds the LMS-specific pieces on
 * top of it: touch-friendly hit areas, the mobile header brand mark, the
 * floating bottom navigation dock (student and admin), and a few
 * overflow/scaling safety nets for modals and embeds. Every rule here is
 * scoped to < 992px (Bootstrap's `lg`) or narrower, so nothing here changes
 * the desktop layout.

   The batch/status pill, rendered in normal document flow directly under

   own single row is nowrap (see .lms-header-title below) and has no room
   left for the pill once the action icons moved into that row alongside
   the hamburger/logo, so it lives here instead. A normal-flow sibling of
   <header>, not a descendant of it, so it can never be clipped by or
   overlap anything below it (previously, wrapping inside header-main's
   fixed-height box let overflow spill down over the page content beneath
   it — most visibly the dashboard's blue hero card). Hidden at >= lg,
   where the single-row desktop header already has room for the pill inline.

   second line and overflowing the fixed-height header. Overrides
   style.css's own `.head-left h4` 2-line -webkit-line-clamp rule, which
   doesn't leave the icons enough guaranteed space since it lets the title
   claim a full second line before truncating. */
