/* Phone stack (18 Oct 2026, Adam): on a phone or tablet (900px and below) a section made of tabs becomes a plain stack, each
 * item a heading and sub-line with its own picture directly under it, then its words. The tabs and stage are hidden (display:none,
 * so their pictures never download) and the stack is hidden above 900px (so its pictures never download there).
 * Markup: <div class="mstack" data-mstack><article class="mstack-item" data-frames="a|b" data-alts="x|y" data-step="3000">
 * <h3 class="mstack-head"><span class="mstack-num">01</span><span class="mstack-name">Name</span><small>Sub-line</small></h3>
 * <figure class="mstack-fig"><div class="tv"><div class="tv-screen"><img class="is-on" src=a loading="lazy"></div></div></figure>
 * <p class="mstack-text">Words</p></article>...</div>. Put the .mstack after the .scr it replaces (inside the same .wrap) and add that
 * section's tabs and stage to the hide rule below. The section's own eyebrow, heading and intro (.scr-rail .section-top) stay.
 * Embedded AI (#ai) follows it with demos instead of stills: one player (ai-home.js) moves into the item most in view and plays
 * that part; the other items show their part's opening picture (claude-demo/posters, set by ai-home.js only at 900px and below)
 * as a "Play demo" button. Its links and caption line end the stack. */
