   Rules:
   - Pixelify Sans is window chrome only (see 00-foundation.css tokens).
   - Paragraph text is 15px or more. Small labels and table cells are 13px or
     more. SVG text is 12px or more.
   - Headlines wrap between words, never inside them.
   - The first screen is one question, one answer and one chart. Everything
     else is folded, and the agent panels (WebMCP queue, receipts) stay
     hidden until asked for. */
