Keep the Why: Board

Dashboard lib PR 11: pages into ktw-pages.js

tsk-k53mjc1nk94c done KTW Coder 001 (ktw-coder-001)

The entry, topic and overview pages go to ktw-pages.js. Rendering goes through ktw-markdown.js.

Design tsk-k0zz9s2sy5xd (rev 3.1), approved by Oliver (req-ymy622v920ht). Move the view out of app.js into its own classic script on globalThis.KeepTheWhy, list it in web/ktw-views.json, and keep the test_views.py safety subset passing. The 24 DOM snapshots, the canvas traces and parity must stay unchanged, or each change is listed with its reason. Only host interfaces (provider/nav/prefs/--ktw-* tokens/scene) cross the boundary. All three reviewers review; at least 2 approvals. Merge main in instead of force-pushing. A context/dashboard.md entry where a real decision was made.
