/* Systems section (added 2026-11-04): what Valento connects to and how the data is protected, between
   the feature cards and "Three phases". Centred .h-big headline, then two rows of ten system tiles wired
   into one Valento block between them (option 1 of six), one line for everything else, then four small
   duotone illustrations (style F of seven), both picked by Shahad on 2026-11-04.
   The wires are SVG paths with fixed coordinates on the 1480 x 296 canvas (rows 0-88 and 208-296, rail at
   y 148, block 264 x 64 at x 608-872), so the row and block sizes below are fixed too. Plain lines only:
   the endpoint dots and the moving dots were removed on 2026-11-05 (Shahad).
   Authored at 1920 design pixels; the narrow layouts at the bottom apply below 1100 px only. */
