   LOADING STATE (CANONICAL PATTERN)

   CANONICAL LOADING PATTERN FOR BUTTONS:
   - Use .is-loading class on button
   - Button stays same size, becomes disabled
   - Inline spinner icon (rotating sync) + text
   - NO pulse animations on buttons/CTAs
   
   Example HTML:
   <button class="btn btn--filled is-loading" disabled>
     <span class="md3-inline-spinner material-symbols-outlined">sync</span>
     <span>Saving...</span>
   </button>
