/* ---------- AI-Assisted Workflow (Figma 342:1417) ----------
   Three mini case studies. Each opens with a Display/M header (divider to the
   page edge), an eyebrow label + Body/M brief, then image
   blocks across the page margins: 48px below the brief, 24px apart. Projects are
   128px apart. Image labels are eyebrows, 8px above each image. Prompts are
   Body/L with a Signal Orange rule. */
