// TRF0 node payload (40 bytes).
// Field naming for the first 16 bytes is based on empirical checks over the mission .trf set.
// ResearchCost/ResearchTime look gameplay-related (strong mutual correlation and upgrade-level scaling).
// ViewPosX/ViewPosY behave like 2D layout coordinates; very large Y outliers are mostly unnamed/off-screen nodes.
