The gate hashed each component's entire emitted CSS, so any unrelated style change
in these four files (Regions giving three :host rules position:relative) failed it,
and could pass only by re-baselining a guard that exists to prove something else.
It now hashes what library/styles/portedGlobals.js emits, found in the executed CSS:
each cyrillicHeading and strongMedium rule with the selectors in front of it, and
each scrollbar-gutter declaration with its rule's selector.
Re-baselined on the tree the old gate passed on. Proven both ways: re-scoping
GoalCard's strong rule, changing the module's Cyrillic letter-spacing and dropping
a file's ported rules each fail it; --write refuses to baseline an empty block.
