   ATHAR · أثر — About (about.html)
   A small, quiet exhibition of one word (polish, 13 Oct 2026). Five rooms, one idea each:
     1 Hero        — "A trace worth leaving." beside the trace itself: the deck's cover photo
                     (roots raking a fingerprint into the dune), hung as a print in an ivory mount;
                     it opens from the fingerprint's core outward.
     2 The word    — أثر, large and textured, beside what it means.
     3 The mark    — the memorable moment: a specimen plate. The logo draws itself (print, tree,
                     name) and each part is named on a leader line as it appears (about.js).
     4 Principles  — three, on hairlines, with the deck's sage icon discs.
     5 Founders    — one line; then the shared green closing band.
   Shared patterns (.page-hero contract, .closing, .disc, .reveal) come from athar.css. Logical
   properties only, so Arabic mirrors; the logo itself is never mirrored.
