   Noscript / JS Corralling

   Pattern for graceful degradation when JavaScript is disabled.

   Usage: Add this in <head> of pages requiring JavaScript:

   <noscript>
       <style>
           .js-only { display: none !important; }
           .noscript-msg { display: block !important; }
       </style>
   </noscript>

   Then mark JS-dependent elements with .js-only class
   and fallback content with .noscript-msg class.
   ======================================================================== */

/* Elements that require JavaScript to function */
.js-only {
    /* Visible by default (when JS is enabled) */
}

/* Fallback content shown when JavaScript is disabled */
.noscript-msg {
    display: none;
}

/* Override .blocked's display when combined with .noscript-msg */
.noscript-msg.blocked {
    display: none;
}

/*
   The actual hiding/showing is done via <noscript><style> block
   in each page's <head>, which overrides these defaults:

   .js-only { display: none !important; }
   .noscript-msg { display: block !important; }
   .spa-island__fallback { display: block !important; }

/* ========================================================================
   SPA Islands

   Inline containers for React/Vue/etc to mount into.
   Islands participate in main's scroll - no internal scrolling.
   Static content around islands remains accessible without JS.

   Usage:
   <div class="spa-island" data-island="dashboard">
       <div class="spa-island__fallback">
           <p>Interactive dashboard requires JavaScript.</p>
           <a href="/api/data.json">View raw data</a>
       </div>
       <div class="spa-island__loading js-only hidden">
           Loading...
       </div>
       <div class="spa-island__root js-only"></div>
   </div>

   React mounts to .spa-island__root, shows loading first,
   then hides loading when hydrated. Fallback shown via noscript.
