- _computeConjunctions(planets, threshold=8) detects conjunct pairs
- Tick lines (nw-planet-tick) radiate from each planet circle outward
past the zodiac ring; animated via attrTween; styled with --pri* colours
- planetEl.raise() on mouseover puts hovered planet on top in SVG z-order
- Dual tooltip: hovering a conjunct planet shows #id_natus_tooltip_2 beside
the primary, populated with the hidden partner's sign/degree/retrograde data
- #id_natus_tooltip_2 added to home.html, sky.html, room.html
- _natus.scss: tick line rules + both tooltip IDs share all selectors;
#id_natus_confirm gets position:relative/z-index:1 to fix click intercept
- NatusWheelSpec.js: T7 (tick extends past zodiac), T8 (raise to front),
T9j (conjunction dual tooltip) in new conjunction describe block
- FT T3 trimmed to element-ring hover only; planet/conjunction hover
delegated to Jasmine (ActionChains planet-circle hover unreliable in Firefox)
