/* ============================================================
   Takshin Technologies — site styles
   World: the builder's drafting room. Cool technical paper,
   graphite ink, oiled-bronze accent. Signature motif: the kerf —
   a 45° cut (takṣ: to hew) on plates, dividers, and the mark.
   Type: Inter Tight (display/body) + JetBrains Mono (annotations),
   shared with the ClavionX product DLS so the family reads as one.
