/* ==========================================================================
   XSim  (/products/manufacturing/photonics/xsim-photonics/)

   The product page under Photonics, and the last product page linked from
   anywhere in the build to be built. The slug keeps v4's "xsim-photonics";
   the page itself names the product XSim, as its structure doc's H1 does and
   as Tech-X does everywhere (open items K77 and PH1).

   Nine sections, the shape of the three FTCO tool pages. NO NEW COMPONENTS -
   everything is product-family.css. What is left here is a band run, three
   column counts and the section anchors.

   Band rhythm is the homepage's: 48 / 64 / 80. Bands alternate white and
   --ps-color-neutral-2-100; --ps-color-neutral-2-000 is reserved for the
   conversion band. No two adjacent bands share a tint.

     §1  banner        white          §6  proof          neutral-2-100
     §2  what it does  neutral-2-100  §7  evaluate       neutral-2-000
     §3  capabilities  white          §8  FAQ            white
     §4  works with    neutral-2-100  §9  related        neutral-2-100
     §5  applications  white
