/* ============================================================
   QUANTUM LONGEVITY — Medicine 3.0 design system
   Website Master Blueprint v1 §5, ported from the prototype.

   Palette : navy ground #0B1D2E · paper #F3F7FA · Red Mind #C0432B
             Blue Mind #1F6FA8 · Purple #6A4C9C · Quantum violet #8F7FD1
             Earth ochre #9C7A46 · Air #5C93B5
   Type    : Fraunces (display) · Manrope (body) · IBM Plex Mono (markers)
   Devices : the colour-arc bar · the italic "flowy line" under every section
             mono biomarker chips · body-coloured dots that fill as ticked

   Colour is addressed through --bc (body colour) / --bs (body soft) /
   --mc (mind colour) / --fc (frequency colour) so one component works in all
   five body colours and in dark mode.

/* ================================================================
   VISUAL LAYER — diagrams, motion and depth
   ================================================================
   Client feedback: the site read "like a PDF document" - too plain,
   too little graphic content, not interactive enough.

   There is no usable photography yet (blueprint §10 item 4 is still
   outstanding), so the visual weight here is carried by drawn SVG
   diagrams of Dr Arpit's actual IP - the five bodies, the flow cycle,
   coherence, the nine frequencies - rather than stock imagery. Every
   graphic is inline SVG driven by the same colour tokens, so it works
   in light and dark mode and costs no extra request.

   Where a real photograph belongs, .photo-slot marks the spot with a
   branded placeholder and an art-direction note, so the team knows
   what to shoot and the image drops straight in.
