USGS has no colour equirect for Europa/Callisto/Titan/Phobos/Charon, so those
mosaics shipped grayscale. Multiply each by its characteristic hue at render
(bodies.js `tint`; moons.js tint-preserving loader keeps the real surface detail,
adds the iconic colour — Titan orange, Europa/Charon tan, Callisto/Phobos warm).
Io/Ganymede/Triton stay true USGS colour (white multiplier). Flagged in CREDITS as
a directorial (non-data) choice per Part ω.2. User-directed ("colourise the moons").

- source 8 public-domain equirectangular mosaics (io/europa/ganymede/callisto/
titan/triton/charon/phobos) from usgs astrogeology, downscale to 1024x512 jpg
(0.92 mb added total, each <=143 kb); credits.md lists source/mission/license
- bodies.js: texture field on the 8 sourced moon entries only
- moons.js: load textures via ctx.loadTextureInto (same path as planets.js, so
the moon's own 2k map also renders now); flat-color 404 fallback preserved
- moons.js tick: tidal lock rotation.y = 2pi*(jd-J2000)/period + pi (signed
period gives retrograde spin for free)
Stage 6. almanac.js: on-focus grimoire card — physical fact sheet, hand-written
prose (grimoire voice), MODELBEAST portrait, and LIVE computed facts free from the
ephemeris: distance from Sun & Earth, sunlight age, vis-viva orbital speed, day &
year length. Earth easter egg → GODSIGH world view (:8137). Real Solar System Scope
2k textures (CC BY, 6.1 MB) now paint every world + the Milky Way skybox; ephem
gains semiMajor() for vis-viva. Generated grimoire portraits (FLUX via MODELBEAST,
10 bodies, seed logged in art/PROMPTS.md) are the AESTHETIC layer only — real
worlds get real maps (truth boundary). README with layer table + quickstart +
verify; docs/hero.jpg. Also lands the Stage-3 planets label fix (obj.visible).
Gate: every clickable body has a card; quickstart works from a fresh clone.
