The off-screen rule for clicks was described in 3f0abf8 and in the pull request, but only its
comment was committed: pickAt still let the slop reach past the frame. The mutant that was said
to catch it matched nothing, and an unrelated flaky test failed instead. The frame test is now in
pickAt, before the slop, and its test fails without it (star at NDC 1.01, click at 0.995).
Venus, Uranus and Pluto turned forwards: Horizons states a retrograde spin twice, by a negative
rate and by an obliquity over 90 degrees, and both were applied. The period's sign is now used
only when no obliquity is known. Measured on the live markers, spin axis against orbit normal is
cos(obliquity) for each: Venus -0.999, Uranus -0.135, Pluto -0.494, Earth 0.917.
Moons listed as rates rather than "Synchronous" drifted about 5 degrees an orbit and Titan did not
turn: every moon is now locked at its Kepler period. Pluto's obliquity comes from IAU WGCCRE 2015,
Horizons gives none.
Also:
- the star's light is white at pi, not a warm 2.2 that left the photographs dim;
- procedural textures are 128x64, not 512x256 that froze the main thread ~60 ms a body;
- Io, Pluto, Titan and Deimos lose their "maps", which were disc photographs with black sky;
- an exoplanet with only a mass gets a radius from it (M^0.55, capped at Jupiter), not Earth's;
- the clock knows when it has left the present even once back at real time, so the date and
"Back to now" stay up.

The view had one rotation in it — the planet on the detail page, at 0.08 rad/s,
a number with no source. Nothing in the system view turned at all.
The data was already on disk: every cached Horizons page carries how its body
spins, in one of five forms. The rate in radians per second is preferred where
it appears, because it is signed — that is how Venus and Uranus are known to
turn backwards — then a period in hours or days, then the `9h 55m 29.711 s`
the giant planets use, and finally the word every major moon here carries
instead of a number: Synchronous. A tidally locked moon's day is its orbit, so
Kepler supplies it from the elements already parsed and the parent it goes
round.
Seventeen of the eighteen bodies come out within 1% of their published period —
Earth 23.934 h, Jupiter 9.925 h, Venus -5832.5 h, Io 42.5 h, Callisto 400.5 h.
Titan is the exception: its page states no period at all, so it is left still
rather than turned at an invented rate.
The axis is the orbit normal tilted by the obliquity about the orbit's
ascending node, which is where an obliquity is measured from and the only line
in the orbit the elements name. The phase at the epoch is published for none of
these bodies, so the face turned toward the camera is not a claim; the rate and
the direction are.
At true rates nothing is visible moving — Earth turns 15 degrees an hour. A
clock the reader can run faster is the next piece, and the audit asks for it
anyway.
