0061 Printish

added css for print formatting.

defaults to system-set monospace.

one reason is accessibility, another is that firefox (and derivatives) can save the printer output as a pdf.

this requires reorganizing the site a bit (because hugo hates @import???).

code needs “refactoring” again anyway.

i would totally force the printer output to be an 8-bit version of punched tape if the standard actually existed.
