idea: minimize html in build mode

[isaacl]

Is your feature request related to a problem? Please describe.
Should vite build minify generated html files? Downsides:

• they're harder to read, though devtools can pretty print.
• adds time to the build

Upside:

• potentially loads faster

Describe the solution you'd like
pass html through something like html-minifier or roll something simple from scratch

Additional context
Seems logical given that js and css are minimized in build mode.
