   Design notes
   - Structure comes from rules and whitespace, in the manner of a paper's tables. No cards or pills on content.
   - One accent: the red dot (a data point). It marks the wordmark, the current page and ongoing roles.
   - A Charter / Sitka / Cambria serif for reading and headlines, the system sans for dates, labels and controls.
   - One header at every screen size: wordmark, quick links, Contact and a Menu button that lists every page.
   - No font files and no external requests.
