/* TheseusDSP marketing site -- deliberately plain static HTML/CSS, no
   build step, no framework: cheapest possible thing to host (any static
   file host) and cheapest possible thing to maintain. Palette/accent
   mirrors the plugin GUIs themselves (dark neutral chrome, rich green
   accent, translucent top bar) for brand continuity between the site
   and the actual products. */
