Swiss layout: flush-left type, numbered rows, hairline rules, no cards. Anything numeric sits in a dark instrument readout. Colours are sampled from the pixel-art characters.
Questions for you
Do the dark readout panels feel part of the page, or pasted on?
Is Archivo the right base to customise, or does it read too generic?
Light or dark as the default, for use in a gym?
Is anything competing with the numbers you type?

Numbers are real history except today's sets, the target and the cue, which are placeholders. Fonts are stock Archivo and IBM Plex Mono, to be customised.
