Order some relevant reference designator. Use JP for all jumpers. Place
silkcreen neatly. Add some custom silk screen. Remove heat sink corner
marks on silk screen.

Use JLC7628 impedance values to get more options in color selection.
Also this leads to slightly wider traces typically, and it will be
easier to switch back to JLC2313 or the like than the other way around.
Also swap placing of HDMI/SW2 and rotate the heatsink by 90° for easier
routing.

Use minimal track width/gap of 0.127mm. Use impedance calculated using
the JLCPCB calculator for the 85Ohm/90Ohm differential pairs and 50Ohm
single trace.
For the 100Ohm pair the JLCPCB calculator does not allow to specify a
track gap which leads to a track width of 0.127mm or bigger. Hence for
this I used https://www.mantaro.com/resources/impedance-calculator.htm
(with Er 4.05, h 0.095, t 0.035).
Also use vias of 0.45/0.2mm by default.

Improve/fix most silk screen placement of most parts. Decrease size to
0.8mm by 0.8mm and 0.15mm thickness which works for most PCB manufacturers.
