/* BrassPause public site. One stylesheet, no scripts, no webfonts, nothing
   third party. A privacy page that fetches a font from another company in
   order to say it collects nothing is a page that hands the reader's address
   to that company. So: system fonts only, everything served from Pages.

   The visual idea is a lit music stand in a dark practice room. Charcoal-navy
   ground, one warm brass rule running down the left of the page like the lip
   of a stand, ivory type. Prose is set in the system serif, the way printed
   studies are; every duration is mono with tabular figures, so 00:37 has the
   same width wherever it appears. There is no sans-serif on this site.

   Deliberately unlike the sibling GlazeTag site, which is light paper, sans
   body text and cobalt. Different app, different room. */
