The previous east-flavored composite (tight-crop east region + lunar
texture overlay) was honest but visually limited: 38-px source moon, no
real terminator shadows on quarters, and a faint upscaled-halo
background that was less compelling than just a clean lunar render.
New flow:
- East stays the witness (verifies the moon was visible during the
collection window) and supplies the timestamp.
- moon_dialamoon.py fetches the NASA SVS Dial-a-Moon render for that
exact UTC hour. Free, public-domain, real-physics: correct phase,
libration, and crater shadows for any timestamp.
- moon_composite.render_phase_closeup() places that render at ~92% of
frame height on a 1920x1080 black background -- the long-telephoto
look the user asked for.
- One API call per phase event (~36/year), cached forever in
moon-ref/dialamoon/.
Quarter moons now show real 3D crater shadows along the terminator,
which the prior algorithmic phase-shadow couldn't simulate from a
full-moon reference.
Adds MOON_REQUIRE_EAST_VERIFY=true|false toggle so the user can choose
"only post when east saw it" (default, current behavior) vs "post every
cycle regardless of weather over east."
Drops the install-time lunar reference download (no longer needed) and
the now-unused per-phase phase-shadow path stays in moon_composite.py
for reference / future reuse.
