/*
 * Shared styling for the QuantDesk site.
 *
 * Design intent: this sells financial software to people who will trust it with
 * a brokerage account. Gold-and-crimson "conquest" styling is exactly what a
 * scam looks like, so the Roman theme is read as MARBLE, ORDER AND DISCIPLINE
 * instead — which is also what the product actually is (rules, hard stops, no
 * profit share). Restraint here is a trust signal, not timidity.
 *
 * Imperial red is reserved for risk callouts only. It is semantic, never
 * decorative — if it is red, it is about losing money.
