Blurred forest-link text and popup on hover in firefox
I noticed that when I hover over links under forest-link container, both the highlighted text and the tags popup becomes blurred when using Neuron generated static site in firefox.
It should be reproducible in latest firefox, if not, I can try to add more specific information or try to resolve it myself.
Attached picture shows the problematic menu. Note that when taking a screenshot, the blur disappears.

Probably something to do with the opacity setting for deemphasized elements: https://github.com/srid/neuron/blob/943d15ee8a0091af53ded079d3b676dbd0bc54a9/neuron/src/lib/Neuron/Web/Zettel/CSS.hs#L129-L132
From my experimenting, it is related to the rotate transform, where the tree gets rotated around origin which falls between pixels.
I didn't find a clean way to solve this yet, but it does help to change some of the relative em units into px units.
