/* ────────────────────────────────────────────────────────────────
   TOOL — YouTube Lesson Generator

   Built on the site's own tokens (tools.css :root), so the lab reads
   as part of the catalogue rather than a bolted-on app. The old
   standalone plugin shipped a slate-and-blue Tailwind-ish palette
   inline in the shortcode, which looked like a different website.

   ⚠️ Every button here names its own background. The site's base
   .at-btn sets geometry and type but no fill — a bare .at-btn is
   painted by Astra's own button rule, which is theme blue on an
   indigo site. Variants (--primary, --ghost, --tiny) bring their own.

   3.0.0  2026-08-17  Rebuilt for the platform.

/* ── the panel's own width ──────────────────────────────────────
   The standard tool panel is 860px, which suits a form with one
   textarea in it. This tool is a video with a transcript beside it,
   and at 860px the pair sit in a narrow column under a much wider
   header — the page reads as though the content slipped off centre.
   1180px is not an arbitrary widening: it is exactly the width of
   .at-page__inner, the column the header, the breadcrumbs and the
   related-tools grid all already use, so the lab lines up with them
   rather than introducing a fourth width. Not `layout: app`, which
   removes the max-width entirely and would overshoot the header.  */
