/*
 * PT. Intilab Instrumen Analytikal: consolidated stylesheet
 * Design Read: B2B laboratory procurement landing page for QC/R&D managers and purchasing teams,
 * technical-ledger language with a glass accent, dial ENERGY 2 / RHYTHM 3 / MOTION 1.
 *
 * Glass dose (R-10): backdrop-filter is used on exactly 2 elements, the Hero Quick RFQ card and the
 * Directory Selection Tray. Reason: they are the two floating, action-driving surfaces. Everything else is solid.
 * The hero has a fixed dark brand-glow backdrop (logo navy and green) so the blur has real color to refract (R-01).
