/* Memoir & Oral History — shared stylesheet for the memoir landing pages
   (/journal/memoir.html + /zh/journal/memoir.html) and every memoir article
   (rendered through _includes/layouts/memoir-article.njk). Loaded per-page via
   the `extraHeadCss` hook. Matches the locked sepia / Cormorant + EB Garamond
   Journal system; Traditional pages swap the serif to Noto Serif TC via html[lang].

   Visual intent (brief §21): archival, personal, restrained, text-led. Images
   are optional — the no-image state is a deliberate design, never an empty box. */
