/* Interactive Egypt port map (component). Markup: scripts/templates/port-map.{en,ar}.html; behaviour: assets/js/port-map.js.
   States on .pmap: is-live (selector ready), is-inline (map SVG inlined, lanes drawn), is-drawn (lanes animated in),
   is-fallback (inline failed: image + list). Without JS (no html.js) the whole map and every panel show as a list.
   The map is a drawing in map space: it never mirrors in RTL; the page layout around it does. */
