📖 almanac: knowing — info panel, live facts, grimoire art, real textures, README (opus)

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.

+locally from Keplerian elements; network layers are additive and fail soft.

+## Controls
+
+- **Focus** — click any body (or use the Focus menu) → the camera flies into orbit
+  around it; breadcrumb `SOL ▸ JUPITER ▸ EUROPA`; `Esc` steps out one level.
+- **MEGA / TRUE** — toggle the scale mode; the transition animates over ~2.5 s.
+- **Body scale** — 1× / 100× / 1200× radius exaggeration.
+- **Time bar** — NOW, play/pause, reverse, rate presets (`1× · 1 min/s … 1 yr/s`),
+  and a scrubbable 1800–2050 timeline. A **LIVE / SCRUBBED** chip mirrors GODSIGH.
+- **Info panel** — appears on focus: a grimoire card with a physical fact sheet,
+  hand-written prose, a stylized portrait, and **live computed** facts (distance
+  from Sun & Earth, sunlight age, orbital speed, day & year length). Focusing Earth
+  reveals a link to the GODSIGH world view.
+- **Shareable URLs** — the view serializes to the hash
+  (`#f=<body>&t=<time>&s=<mega|true>&L=<layers>&cam=…`); paste one to reproduce a view.
+- **`?debug=1`** — frame-rate / scale readout.
+
+## Architecture
+
+No build step, no framework, plain ES modules. One module owns the truth→view
+transform (`scale.js`); every position is computed in real heliocentric J2000
+ecliptic AU first (`ephem.js`) then compressed. A **floating origin** subtracts the
+focused body's position in float64 before writing to the scene graph, so a focused
+planet never jitters at close zoom.
