/* ============================================================================
   MIRA page header — the bar at the top of every page inside the app shell.
   Rendered by Views/Shared/_page_title.cshtml. See design/page-header-redesign.html.

   Deliberately NOT in app.min.css: that file is the vendor theme, and a theme
   update would take these rules with it.

   The shape is one line at every width. What changes between sizes is only what
   is SHOWN — nothing is repositioned, so the bar never changes height between
   pages and the content below it never jumps.
   ============================================================================ */

/* The theme sets .main-content{overflow:hidden}. `hidden` makes an element a scroll
   container, and a sticky descendant then sticks to THAT box — which never scrolls —
   so it silently never sticks. `clip` clips exactly the same pixels without creating
   the scroll container, which is the whole reason it exists. Nothing else changes. */
