/* Porch Light site, in the app's language (docs/Porch_Light_Design_Spec.md Section 3, docs/design/DESIGN.md).
   Paper surface (evening in dark mode), two type sizes: a system-serif display line and
   system-sans body. No bold, no boxes, no shadows; one radius. Left-aligned. The warm light
   color marks a light that is on and the app's one filled button; the site has neither. */
