/* ==========================================================================
   "WATCH IT IN A MINUTE" — added 31 Oct 2026 (Explainers sub-session 2).
   The Why change story, narrated by PK, in about a minute. OPT-IN: the two
   story paragraphs stay the default, and nothing for the player
   (js/ai-explainer.js, media/ai-explainer.mp3, the Anton face) loads until
   the button is pressed. The square player then takes the paragraphs' place
   in the left column; "Close and show the text" puts them back. The
   tap-to-reveal list on the right is not touched.

   The .explainer rules mirror the phone page's block in service-v2.css,
   which this page does not load; if the two ever change together, they are
   the candidate for a shared file. Only the frame, the buttons and the focus
   rings are the site's. INSIDE the frame the player keeps its own
   editorial-collage look on purpose, so the colors below the stage are its
   own. Source and decisions: prototypes/voice-explainer-ai-tab/index.html.
