<!--
Phase 23 Report View — foreign sciences section. Renders one
sub-table per race, mirroring the legacy "<Race> Sciences" layout.
Sorted alphabetically by race name (the decoder already produces
the (race, name) order); the sub-table groups are built here so
that anchor navigation to the section lands on a single visual
unit even when the section spans many races.
