/* ============================================================================
   Mexican Summer — shared component layer
   ----------------------------------------------------------------------------
   Loads after tokens.css and before a tool's own <style>, so anything a tool
   redefines at equal specificity still wins.

   Canonical page skeleton — every tool should open with this header so the
   back-link, the title and the header rule sit identically across tools:

     <header class="app-header">
       <div class="header-inner">
         <div class="header-lead">
           <a class="home-link" href="../index.html"><span class="caps">← Index</span></a>
           <h1 class="tty"><span class="caps">Tool Name</span></h1>
         </div>
         <div class="header-tools"> …buttons… </div>
       </div>
     </header>

   House rules worth knowing before adding to this file:
     • Containers are square-cornered, buttons are fully round (500px). That is
       the site's own logic — image blocks are hard-edged, pills are pills.
     • Avant Garde for anything set in caps (labels, buttons, headings, values);
       Helvetica Neue LT Pro for running text and inputs.
     • Orange is the only interaction colour: links, hover fills, focus rules,
       active tabs. Amber is reserved for warnings.
