/* /advisors/platform. Family ADVISORS "Structure": the cool half of the light only (cyan to violet and their pastels),
   graphite lines, wide technical grammar. Signature: INTERFERENCE (a ripple tank: four emitters, one per tool category,
   out of phase make a restless field; in phase they focus as one pattern on the sign-in).
   One custom property drives the overlays: --c on .tank, 0 = separate sign-ins, 1 = one sign-in. Default 1 = the poster
   (JS off and reduced motion show the focused state). Geometry is normalized to the plate and shared with
   assets/platform.js (GEO) and tools/paths.py: landscape sources x .145 y .2/.4/.6/.8, focus (.735, .5), aspect 2.6;
   portrait (<= 760 px) sources y .15 x .2/.4/.6/.8, focus (.5, .68), aspect .64. */
