Each site is one Watermark investigation. The page color says what opens; the campus line is the build on the ground — two different clocks.

The chart set

Seven SSR-SVG primitives, one palette. Forest carries the data; the evidence colors stay reserved for evidence. Every figure is monospace and provenance-first — a chart here is just another way to show a number you can check. No JavaScript, no charting library.

Figures shown are illustrative sample data for the preview, not findings; each primitive takes plain data props and an evidence tag, so a chart carries its provenance exactly like the figures it visualizes.
