/* Timm Gries - academic site, v0.3.
   Left rail (photo + identity) / right column (about, papers), the classic
   academic two-column. Square photo corners per author. Light-committed,
   Palatino to match the job-market packet, navy accent, no hairline rules.
   Deliberately NOT PaperMod (cohort-mate uses it), not a link-dense layout. */
