okaay, wiggle-progress... 1st image is left end, i think CX and TX0 i can shorten even more, there's definitely plenty of space there, big gap.
2nd image, right end, this is where i've added intra-pair wiggles at the 45 degree bends. i can't get away with a proper 4-turn using 45 degrees, PADS goes "nope that's too short a trace, i'm gonna assume you want a straight line instead" - there's probably an option somewhere for that but i've not found it. alternatively i can add in a (curvy) accordion....
anyway those wiggles are done by hand, some of them aren't pretty but in mil those traces are now nearly all to within 0.01 mil. i cheat a little and have made some of the corners in places a very very tiny arc, where you get better fine-grain control over the amount it takes off.
HTXCN just before the diff-pair vias at the end i'm a little concerned about, it looks a bit too... sharp-angled to make me feel totally comfortable... not a lot of space... i tried a single wiggle and it went too far away from HTXCP for me to feel happy about it.... put in two much smaller wiggles instead...
GND i'll remove as the absolute last thing.
