/* KOLLAZ Software — DEMO C "The Firm".
   Stark editorial: pure white, black ink, oversized Noto Sans display
   type at architectural scale, Swiss grid, hairline rules, the product
   ledger as a numbered index, the seal as a printer's colophon.
   No shadows. No gradients (the primary button's mandated hover shine
   sweep is the single exception, and it is a flat white pass).
   Same words as the live home; only the design speaks differently. */
