   REL 320: Sexuality and Gender in Buddhism — Stylesheet
   Theme: plum / copper, with a layered lotus-petal motif rendered as
   restrained line art — a recurring image across the figures this course
   studies (Tara, Guanyin, female bodhisattvas) without leaning on
   gendered color cliché.
   Edit the CSS custom properties in :root to retheme the whole site.
