The Sun lights the globe where it really is (wwwroot/js/sun.js, the Astronomical Almanac's low-precision solar
coordinates): the day map shaded by the Sun's height and the Earth–Sun distance, warm city lights on the night side,
and a twilight blend about 13° wide between them. It shows now, refreshed every 30 s, or the moment of the hovered,
focused or pinned post: a click on a card pins it, and the subsolar point travels there the shorter way round. The
panel's top corner shows that moment, the phase of the day and solar time at the post's place, and the season in its
hemisphere (or in both, for a post without a place). Its tooltip shows the subsolar point, declination, axial tilt,
distance, irradiance, day length and the next equinox or solstice.
Land borders are thin paths. Country names are in the reader's language and appear as the camera comes closer:
largest countries first, away from the globe's edge, never overlapping. They come from world-atlas 2.0.2 (Natural
Earth 1:50m), prepared by tools/globe/prepare-countries.py, and are vendored with their hashes in SOURCES.md.
