/* 百年一遇 — one stylesheet, no framework.

   Water: a deep blue-green ground, one clear blue for the curve you are on,
   and one warm rust for the curve a rising hazard puts above it. The gap
   between those two colours is the entire climate-adjustment argument, so
   nothing else on the page is allowed to be saturated.

   Bar widths come from generated classes at the bottom of this file rather
   than from style attributes, because the Content-Security-Policy in the page
   drops an inline style silently — and a chart of zero-width bars reads as a
   design decision rather than a bug. */
