/* ============================================================================
   AI Skill Builder — standalone tool skin. Loaded only by
   pages/ai_tool_templates/ai-skill-builder.php, standalone (no
   assets/styles.css dependency). Scoped under .skb. Aesthetic: an
   approachable build-kit workbench — warm slate/graphite ground, one
   amber-orange accent marking active/assembled state. Deliberately
   low-chrome: soft shadows and background-color shifts do most of the
   separating work, hairline borders are used sparingly (inputs, dividers)
   rather than framing every panel. Mobile-first: base rules are the
   small-screen (stacked) layout; the two-column form/preview layout only
   appears from the lg breakpoint up.
