Seven shadow-root components each carry their own copy of DX Life's
base/_globals.scss rules, because page CSS cannot reach into a shadow
root. Measured first: where the copies overlap they are byte-identical
(the Cyrillic stack 3x, strong{font-weight:500} 2x, scrollbar-gutter 2x),
so this is deduplication, not a fix.
The module exports FUNCTIONS, not strings, and the measurement forced
that: the six copies of the Cyrillic rule share one declaration but have
six different subjects (.rd-goal-card__title, .rd-h2, .rd-title,
.region-card__title, .rl-title x2). A fixed rule string would have to
pick one class and silently stop styling the other five. The caller owns
its selector; the module owns the declaration.
cyrillicHeading takes a selector LIST, not a selector. GoalCard styles
one heading class; RegionSectionCard groups two into a single rule
sharing one declaration block. A one-selector signature emits two rules
instead of one -- the same CSS to a browser, but not the same
stylesheet, and the bar here is unchanged, not equivalent.
Migrated GoalCard and RegionSectionCard. regions-dashboard's two files
port the same rules and stay with their owner; the harness records them
so that migration can run against this same baseline.
The img border-radius rule (_globals.scss:80) is documented as
deliberately NOT ported, because an invisible omission is one that gets
"fixed" later.
PROOF: internal/check-ported-globals-identical.mjs executes each
component's setup, captures the string handed to useShadowStyles and
hashes it. The emitted CSS is byte-identical across the refactor
(987d94b1cd66110d, 897d948b17b21efe, both captured from 45e31f102).
The harness's first version hashed the SOURCE of the call and was
wrong: this refactor replaces a literal with a function call, so the
source changes by construction -- a text-hash gate fails a perfect
refactor and cannot tell that from a broken one. It measured the
artifact when the property under test was the output. It failed exactly
that way on first run.
Shown capable of failing, four ways: dropping letter-spacing, a wrong
font name, 500->600, and splitting the grouped rule into two. All four
go red; restoring goes green. Components that cannot be evaluated are
reported NOT MEASURED (exit 75), never as a pass.
