Plan 79 §H + ratchet 7.
<html dir> already follows the language manifest and the locale probe asserts
it. What was missing is a stylesheet that could follow it: 468
direction-anchored declarations (margin/padding/border-left|right, bare
left:/right:, text-align and float) against 5 logical properties. An RTL
locale today would render a mirrored language inside an unmirrored layout, so
the plan ships plumbing and a ratchet, not a locale. The count is 468 rather
than the plan's grepped 412 because float and text-align are equally anchored.
Also splits `src/i18n/t.js` out of the i18n barrel. The API client's error
mapper imports the bare `t`, and the client is reachable from a node test --
which then loaded i18n/index.js and its `import.meta.glob`, a Vite
compile-time transform that throws under plain node. The obvious fix was the
runtime guard that had just been removed for silently discarding every locale,
so the module is split instead: t.js touches only the i18next singleton, and
index.js keeps initialisation and the glob for browser-only callers.
