/* ============================================================================
   RESEARCH NETWORK — touch-first prerequisite graph
   ----------------------------------------------------------------------------
   develop.js remains the authority for research data, costs, availability and
   effects. This module only takes over the RESEARCH presentation after the
   normal Development renderer has populated materials and tabs. Keeping the
   purchase call routed through devBuy() prevents the visual tree from becoming
   a second, subtly different progression system.

   The old spatial view only ran above 700 px in landscape, which meant the
   game's actual phone orientation silently fell back to the original list.
   This graph is deliberately 2D and scrollable: prerequisite direction stays
   readable under a thumb, cross-branch links are real SVG paths, and every
   node remains at least 52 px tall on a 320 px-wide device.
