I increased a bunch of tap targets to fit the recommended 48x48 sizes
and 56x56 non-overlapping regions, but unfortunately this caused
outlines to overlap with each other. This commit turns these elements
into inline-block elements and makes the necessary fixes to accomodate
this change.
- I forgot to compress xhtml files. fix that.
- Stylistic change: remove unnecessary brace expansions
- Don't repeatedly append to a file; run commands in a different scope
and write all at once.
Move Nu HTML validator filtering into a shell script:
- Return a bad exit code if validation errors are found after filtering
- Remove null-ish values from the JSON output; the final output *should*
be an empty string, since nothing should be reported.
