Generate curve caps with geometry nodes

I'm trying to model a bunch of fiber-optic cables, as seen in many images: with the end of the cable lit.

The cables per se are easy to model: A bunch of curve circles spread around a bigger circle, extruded along a curve.

AFAIK there is no way to control the curve caps, so I used the original cable "slice" from the former paragraph and instanced on the end of the curve with the Endpoint Selection node.

The problem is that I cannot align the rotation of the cap to be aligned with the end of the curves:

I tried Curve Tangent with Align Euler to Vector, and now it faces correctly at the end of the curve, but the rotation along the path doesn't match:

Help me, BlenderExchange! :-) Thank you all

If you go via Curve to Points, that node hands you a rotation: see here – Robin Betts Mar 24 '22 at 17:13

You, sir, are a genius :-D Thank you! Works ferpectly :-) It would be great if you can answer the question to flag it as such. – drmad Mar 24 '22 at 17:39
np. This is almost a duplicate question.. just UV the original's answer, if it helped. – Robin Betts Mar 24 '22 at 17:59
