1. Set a fixed height on the element, preventing the content after the
element from shifting on page load. This uses CSS [container query
length
units](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_containment/Container_queries#container_query_length_units)
as I saw no other way because of the non-linear scaling of the element.
2. Move the "total-contributions" text into the existing vue slot,
eliminating the need for absolute positioning.

Ran most of the Less files through the Less compiler and Prettier and
then followed up with a round of manual fixes.
The Less compiler had unfortunately stripped all `//` style comments
that I had to restore (It did preserve `/* */` comments). Other fixes
include duplicate selector removal which were revealed after the
transpilation and which weren't caught by stylelint before but now are.
