Convert barant.com JET 1.4 marketing pages to jetc/.jtc (local, non-production)

Pulls .page files and shared template infrastructure (mainpagetemplate.temp,
menu.bar, barant.tag, opensource.menu, cart.menu, login.menu) read-only from
barant.com via SFTP into jetc/barant-site/src, then convert.py mechanically
flattens them into self-contained .jet files: linkbutton becomes a plain
anchor link (the old SESSIONCTL PAGE/PROCESS form-postback model has no
equivalent here - each page is its own real #api route now, not a shared
single-form state machine), sectionframe is expanded per its barant.tag
definition, /images/* references are fetched and inlined as data URIs
(APIServer has no static-file serving), and session-gated chrome (cart,
account/admin, login.menu) is resolved to its anonymous-visitor default
state, since no session/DB backend is wired into this conversion.

17 pages convert and serve cleanly end-to-end (verified via a local
apiserver-barant-site.json instance on :8081, kept separate from the
existing demo server on :8080 to avoid a /main route collision with the
earlier hand-cloned barant.jet). Two pages deliberately out of scope for
this pass: davidarant.page (whiledir filesystem iteration) and the
per-topic sub-pages of jet.page (dispatches on an ARGS query param this
conversion does not populate - only the default overview state converts).
vst.page/modular1.page/modular1_patches.page also deferred - they pull
live product rows via sql, a real backend dependency beyond "pages and
their template" scope.

Nothing was written back to barant.com - SFTP access was read-only
throughout, per explicit instruction to convert locally without touching
the original site.
