/**
|
|
* check-i18n-treeshake — each built bundle carries every translation area its code asks for, and (with
|
|
* --sizes) reports what the narrowing saved. Headless.
|
|
*
|
|
* CRITIC-10 (2026-09-26): the build narrows library/i18n's catalogue glob to the areas
|
|
* internal/i18n-areas.mjs finds in the bundle's source graph. Omitting an area a bundle uses would show
|
|
* raw keys instead of text, so this re-reads the BUILT output: every "area.key" literal (and every bare
|
|
* 'area' literal, for keys assembled at runtime) in <bundle>.js must belong to an area the build included
|
|
* for that bundle. Only area-PREFIXED literals are judged here (a bare 'template' or 'options' is also
|
|
* ordinary Vue/JS vocabulary); the build includes an area on a bare literal too, which only over-includes.
|
|
* EXIT 0 pass · 1 an area the bundle needs was left out
