/* Tianyi Zhang — one stylesheet for the whole page.
   The hero is a sky drawn in characters: glowing on the night in the dark theme, in ink on the
   page's paper in the light one. The page follows the theme toggle (dark unless light is pinned); in
   the dark theme its background is the sky's colour at the visitor's hour (--sky, set by theme-init.js).
   Everything around the sky is set quietly: one system sans in sentence case, plain underlined links,
   rows divided by hairlines, no HUD dressing. Hooks used by the scripts are kept: .reveal/.rv-*, .panorama-*, [data-spotify-*], [data-github-*],
   .after-hours-*. */
