progmasoft.com presents Progmasoft as a pool of technology areas instead
of a list of products: languages and compilers, build and packages,
developer tools, quality and testing, identity and access, and
infrastructure. The page has a new hero, a bento of areas, principles and
a developers band that leads to the Progmasoft Console; the products are
one link away in their own catalog.

product.progmasoft.com lists Tala, talac, talafmt, talalint, Tazel, Xide
and Catch3, each with its own page (/tala-lang, /talac, ...) that leads
to the product's site and source. ides.progmasoft.com lists the IDEs and
hosts the Xide site at /xide; catch3.progmasoft.com is the Catch3 site.
The facts follow the READMEs and documentation of the product
repositories: Xide is marked as early work, and Catch3 states that it is
not an official Catch2 release.

The theme switch no longer freezes or flickers. The layout rendered
data-theme="light" on <html>, so every server re-render of the layout
(a language switch) set it back. The control also applied the theme in
an effect after the render while buttons animated their colours. The
attribute now belongs to the bootstrap script and the control alone; the
control applies the theme in the click, and transitions are off for the
two frames of the change.

All new text is in en-US, de-DE, ru-RU and he-IL. The old home messages
leave localization.ts. The proxy maps the new hosts through one table, and
nginx gains their virtual hosts.

The language control no longer reloads the page. It calls a server action
that stores the preference cookie; Next.js then renders the current route
again and applies it in place, so scroll position, theme and client state
stay. The lang query parameter remains for links and for browsers without
script, and is the fallback when the action cannot reach the server. Both
paths write the cookie with the same attributes from one function.

The toggle button is now a language menu, a native select that lists each
language by its own name, and Russian (ru-RU) is the third locale with a
complete translation of every message.

Tests require every locale to have exactly the message shape of the default
locale with no empty text, and cover the cookie attributes and host
normalization. Verified locally: prettier, eslint, type check, tests, the
production build, and a browser run on the apex and ViGet hosts where the
language changed with no navigation and the scroll position kept.

Adopt Patent Grant 1.1, make the apex host canonical while excluding account surfaces from indexing, move the Progmasoft mail boundary into its owning repository, migrate the .NET 10 tests to native MTP, and add persistent light/dark and en-US/de-DE preferences across corporate and account experiences.
