/* Toprak Sam Güven — personal site
   warm-elegant preset, executed as a polished professional dossier.
   Palette in the materials of antiquity (limestone / porphyry / bronze);
   type descends from Roman inscription letterforms (Palatino / Optima).
   One consistent centered section-header system; restrained type scale;
   self-contained (no external asset loads). Outbound links encouraged. */
