/* ============================================================================
   HERO — CONNECTED SERVICES VIDEO NETWORK (right-side hero showcase)
   Isolated component. Every selector is scoped under .hero-video-network so
   nothing here can collide with the rest of the site's CSS. Lives inside the
   existing .sk-hero-figure wrapper — see index.html + the comment above
   js/hero-video-network.js for the integration notes.

   GEOMETRY — one source of truth, no per-item pixel positions:
   - .hero-video-network is a size container; every size below derives from
     its width (cqw), so the circle scales with the column, never the viewport.
   - --hvn-orbit   orbit DIAMETER. The canvas is exactly this big and square,
                   so the orbit is the canvas's inscribed circle:
                   centre = (50%, 50%), radius = 50% of the canvas.
   - --hvn-count   number of services (set by JS from the data array).
   - --hvn-i       a node's index (set by JS). Angle, clockwise from 12 o'clock:
                   --hvn-angle = i * 1turn / count   (10 services -> 36deg)
   - Position:     left = 50% + sin(angle) * 50%
                   top  = 50% - cos(angle) * 50%
     Nodes are sized to the thumbnail only, so the thumbnail's centre sits
     exactly on the orbit; the label hangs off the node on its outward side.
     Connector dots reuse the same formula at i + 0.5.
   - --hvn-node    thumbnail diameter (a fixed fraction of the orbit).
   - --hvn-label-w / --hvn-gap   label width + icon-to-label offset.

   Two label modes, picked by container width (not viewport):
   - "side" (wide):     labels beside the icon on the left/right halves,
                        above/below at 12 and 6 o'clock — matches the design.
   - "compact" (narrow, <560px): every label above (upper half) or below
                        (lower half) its icon, so the ring can use nearly the
                        full width on phones / the 992-1199 laptop column.
