capsite/potluck: plain style after kmjn.org's "Plain HTML with a few bureaucratic gestures"

https://www.kmjn.org/notes/modern_plain_html.html and its stylesheet:
system fonts (Verdana; no Google webfonts), one 800px column,
line-height 1.35, links in the text color with a dotted underline, no
rounding, shadows, or tracking; the header is plain, not sticky glass.
Token overrides live in theme.css; per-page scoped styles unchanged.
