Reciprocal to SOLARGOD's Earth-card link into GODSIGH. A subtle HUD pill
(above the footer, styled to the mode-button family) opens the orrery in a
new tab. The href is rebuilt fresh at click time from viewer.clock.currentTime
via the shared `#t=@<unixMs>` convention, so scrubbing GODSIGH's clock carries
straight through to SOLARGOD's sim time.
- index.html: <a#solargod-link.portal-link> between #layers and footer
- css: .portal-link (matches .modes button; accent on hover)
- ui.js: wireSolargodLink(getMs) — rebuilds href on pointerdown+click
(covers ⌘/middle-click new-tab); Cesium stays out of the DOM module
- main.js: wire it with a getMs closure over viewer.clock
Verified in-browser: button renders, zero console errors, all layers boot;
live click → href tracks the clock; scrub -3h → href exactly 3h behind now +
chip flips SCRUBBED + live layers pause; opening the link launches SOLARGOD
in SCRUBBED state at the passed epoch (its hash echoes the exact ms).
