 * B-Kant site stylesheet (ported from the approved design prototype).
 * Design read: redesign (overhaul) of a B2B medical diagnostics and device distributor site,
 * trust-first clinical language, photography-first layout inspired by the Tesla and Apple
 * DESIGN.md references (VoltAgent/awesome-design-md), built on Bootstrap 5.3.8 (self-hosted).
 * Dials: DESIGN_VARIANCE 5, MOTION_INTENSITY 4, VISUAL_DENSITY 4.
 * Shape rule: buttons and inputs 6px, media and tiles 14px, nothing else rounded.
 * Theme: light and dark through Bootstrap's data-bs-theme attribute (set before paint by
 * theme-init.js). Every colour below is a token; components never hard-code a colour.
