/* =========================================================================
   Latest news strip — paper-surface band, framed top + bottom by 1px ember
   hairlines.

   Choreography (gated by [data-reveal] → .is-in on the section):
     t=0    : ember dot already visible far-RIGHT, halo starts pulsing
     t=0–1s : halo pulses exactly twice with a wide radius, fading at each cycle
     t=1s   : dot begins a 1.4s slide leftward across the strip; as it passes
              each character position the character fades up (rightmost char
              first, leftmost last). Dot fades out as it reaches the left edge.

   Theme companion to the id30-announcements plugin.
   Markup partial:  template-parts/id30-announcements.php
   Char wrapping:   assets/js/id30-announcements.js
   Naming:          .id30-news__*
