zeekay 0f5536b707 hanzo.ai reads in the reader's language, and Arabic right to left
Every word the landing, the header menus, the phone sheet, the footer,
the help corner and the way in (sign-in, sign-up, the reset, the
invitation, the callback, onboarding, the 404) write goes through
@hanzo/i18n's t(): one sentence is one message, its figures, names and
links arguments; copy written as data is phrase('…') where written and
t(label) where drawn. Plans, the chart, the API states and the lines
lib/kai and lib/enso build for the landing do the same.

Right to left: <html lang dir> is set before the first paint (the
package's bootScript first in the head); a figure, clock, range or
price outside a sentence is isolated; sides are logical gui props, the
layout's [data-join] corners logical, a bar grows from the start;
arrows along the line mirror (Onward for "words ->" links). The repo
dates read in the reader's language.

Gates select by slot, never by an English label (rtl, help). New gate
translated.spec.ts: in Arabic the landing at 1440 and 390, every menu
open, the phone sheet, sign-in, sign-up and the app signed in hold no
authored English, nothing scrolls sideways, every range is isolated;
French the same for English's commonest words. What another package
draws with no words prop is listed by name (@hanzo/ui's Footer label,
@hanzo/build's composer row and suggestions).

@hanzo/i18n 0.5.3 (the catalogs: 1,443 keys, every offered locale
complete), @hanzo/app 0.2.1 (the app's words). The link gate imports
the terms versions from @hanzo/app, the one SDK main now resolves.

/**
* A support session, on every page: who the page is signed in as, who opened it,
* and the way out. Mounted once in app/providers.tsx beside Identity.
*
* IAM issues the session no refresh token and caps it at fifteen minutes. The
* earlier session's refresh token is dropped (`isolate`), so the SDK has nothing to
* renew with and ends the session itself sixty seconds before expiry. Every end —
* Exit, that one, or a token found already expired — is `leave`: the token handed
* back to IAM, the tokens cleared, and `/` loaded, where `own()` empties what this
* browser kept for the person. The banner has no dismiss.
