SYZYGY's 104 diamonds clustered into ~1.6% of the 250-yr timeline (invisible in
deep time). Add a second strip under #timeline-outer that maps ONLY the computed
±2 yr window to full width — diamonds live there (same ev-* classes + click-jump),
and the main strip gets a brass bracket marking the window's true extent (1.6%
near, 0.5% in deep time). windowFraction exported + gated. Verified: 22/22
(+band gate); diamonds spread 0.4–98.7%; click-jump works in near AND deep mode;
zero console errors both epochs.

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.

Stage 4. spacecraft.js: Voyager 1/2, New Horizons, JWST, Parker, Juno, Lucy,
Psyche. Fetches VECTORS (heliocentric ecliptic AU) over a multi-year span through
serve.py's cache, Catmull-Rom interpolated per frame; glowing diamond marker +
fading trail + label with live distance from Sun and one-way light-time from
Earth. Fail-soft per craft. Robustness: sequential fetch (Horizons throttles
bursts), serve.py skips caching non-$$SOE (error) responses, and span
auto-recovery clamps START/STOP to a craft's SPK coverage from Horizons' own
"prior to / after" hints (Psyche pre-launch, Juno past coverage) → 8/8 tracked.
Gate: Voyager 1 @2026-07-15 = (-32.07,-136.21,98.55) Δ0.002 AU; JWST Δ0.011 AU
from Earth. verify.html gates 10-11 green.

Stage 0. Zero-dependency serve.py (static + allowlisted horizons/sbdb/cad proxy,
sha256 disk cache with past-span immutability). Three.js via pinned importmap,
logarithmic depth, procedural starfield sky (+ Milky Way panorama swap-in), Sun
with additive glow, OrbitControls, brass-and-void HUD, scrubbable time bar,
central bodyWorld position pass, focus/camera system, hash state. Boots clean,
no console errors.
