/* Dorvy Tech site styles. Fonts: Geist and Geist Mono (SIL OFL 1.1), subset to Latin and common punctuation.
   Aesthetic: calm, evidence-first B2B. Hand-built native CSS; no framework and no design-system package.
   Dials: DESIGN_VARIANCE 5, MOTION_INTENSITY 3, VISUAL_DENSITY 4.
   Theme lock: one theme per page, chosen by the visitor's system (prefers-color-scheme). Sections never invert;
     they only use tints of the same theme (--bg, --surface, --surface-2).
   Colour lock: one interface accent, the logo's teal (#137467, a touch deeper than the logo's #168075 so small links pass
     WCAG AA; #3cbca9 in dark mode). The logo's navy stays in the logo.
   Shape lock: --radius (12px) on every surface, image, button and icon tile; --radius-sm (6px) only on inline
     chips and code. Nothing else is rounded.
   Motion: hover and press feedback only, transform transitions only, switched off under prefers-reduced-motion.
   Z-index scale: header 10, skip link 20. Nothing else uses z-index. */
