Thanks for these patches!

Some thoughts, some of which we already discussed off-list:

  - I'd suggest a wider opening angle for the gauges, so that the gauges
    are a bit more compact and look less like a horse shoe
    To me, 75/285 looked quite good, but this is of course highly
    subjective, so no hard feelings

  - For the percent-label inside the gauge, I think 0 (zero) significant
    digits are okay, for such a 'global' infrastructure gauge two
    significant digits are hardly useful, I think

  - We probably should use full product names (Proxmox VE, Proxmox
    Backup Server) in the card headers, instead of just "PVE" and "PBS".
    The overall text length could become quite long though, so maybe we
    need some other approach for the card title.
