Deploys course 12, "Vibecoding from zero" (9 modules x 3 lessons, route #/vibecoding), to t27.ai. Refs #1807.

How the 27 widgets ship (FR-106). Each widget is a static page with no script: every state is one <section> of one HTML page, a link is a fragment, the CSS :target selector shows the section the address names. A spec pub fn page_<id> writes the whole page through the vendored html_out writer and the shared page_kit frame; t27c gen-text --fn (t27 revision 06522649, the merge of t27#13568) compiles the spec on Actions and writes the bytes to apps/website/public/widgets/<id>/index.html. No page is typed by hand. The eight stateful widgets (four phases, the loop, message loop, plant a bug, read a diff, secrets out, unstuck, test judge) are written out as finite-state machines with a cap on their states; the other 19 are infographics.

This PR

• specs/widgets/views/: page_kit.t27 (frame), view_pages.t27 (the 27 ids), 27 view specs, the vendored html_out.t27.
• .github/workflows/emit-widget-pages.yml: builds t27c at the pinned revision, tests every view, emits the 27 pages, uploads them as an artifact, and fails when a page did not emit or a committed page differs from the emitted one.
• the committed pages, the gallery entries, the course catalog, the lessons and share pages, and the EN and RU blog post.

Foreign-language label: the workflow YAML is plumbing around t27c (one tool call per line), so this PR carries owner-approved-foreign.
