Four right-to-left languages at /ar/, /he/, /fa/ and /ur/ — thirteen in all.
The layout no longer has a left and a right, it has a start and an end: the
margins, insets and corners are CSS logical properties now, so they follow
dir on <html>. Directional glyphs flip; keys, safety codes and session
descriptors are pinned left-to-right so bidi cannot reorder what two people
compare against each other's screens.
Also fixed: the Service Worker was registered as './sw.js', which 404s from
every locale subdirectory, so twelve of the thirteen pages had no worker at
all. And the bundler ran before the dictionaries were generated, so a newly
added language could reach the page ahead of the app that renders it.
The site now speaks German, French, Spanish, Ukrainian, Russian, Chinese,
Korean and Hindi alongside English — 623 strings per language, 5,607
translations, covering the landing page, the key exchange, the chat, group
calls and every error along the way.
Each locale is a real page at a real URL (/de/, /fr/, …), generated at build
time from locales/*.json. That is the whole point: the app is client-rendered,
so a language that only swaps strings at runtime has no address for a crawler
to index and no link anyone can share. Each page carries its own canonical, a
reciprocal hreflang cluster and translated schema.org.
The URL decides the language, always. A stored preference only applies where
the address does not say, and nothing ever redirects on Accept-Language —
that is how sites become invisible to search engines outside one country.
robots.txt and sitemap.xml did not exist before; both are generated now.
Bugs found on the way, each with a test that would have caught it:
- partner logos used page-relative paths and 404'd from any /xx/ page
- post-build stamped ?v= only into the root shell, leaving locales behind
- "Back online" appeared on every page load, not just after being offline
- update timestamps were hard-coded to US format for every reader
- t() threw on a partial window, taking whole components down with it
