/* Celeste — Art : gallery styles
   Aesthetic: a high-end, image-forward artist's portfolio. Quiet, elegant,
   generous whitespace; the work (and the placeholder potatoes) carry all the
   character. Refined serif display paired with a clean sans for body/utility.
   Restraint over decoration. A single warm-stone accent, used sparingly.
   No framework, no external fonts/CDN (CSP is self-only) — websafe/system stacks
   only. Mobile-first; the grid scales up at breakpoints. */
