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.
