 Revision id `phase50_default_modern`. Promotes the phase48 A/B-test design to the default. Two changes, **both required**: the `users.ui_theme` column default becomes `'modern'` (new accounts), and existing rows are moved `'classic'` → `'modern'`. phase48 stored a literal `'classic'` for everyone rather than NULL, so a default change alone would leave every current user on the old design.
 
-**It overwrites a deliberate choice** — phase48 gave no way to tell "I picked classic" from "I never touched it", so anyone who actively preferred classic is moved too. They can switch back from the account menu and that choice then sticks; the switcher is unchanged. `/ui/theme-votes` reads the same column, so the tally reads 100% modern afterwards — capture it first if the numbers matter. `downgrade()` returns *everyone* to classic (individual prior choices were never recorded).

+
+**The A/B test is closed (Aug 2026).** Modern is THE design. The **"Back to Classic Design"** switcher and the admin **"Design Vote Tally"** link were removed from the modern account menu, so a user on modern stays there. Two things were deliberately KEPT: the classic layout still offers **"Try the New Design"** (the only way off classic for anyone still on it — removing it would strand them on a retired design), and `ui.switch_theme` / `ui.theme_votes` still work if visited directly, so nothing 404s mid-request and the tally is still readable at `/ui/theme-votes`. Nobody's stored `ui_theme` was changed by this. `/ui/theme-votes` reads the same column, so the tally reads 100% modern afterwards — capture it first if the numbers matter. `downgrade()` returns *everyone* to classic (individual prior choices were never recorded).
 
 To change the default without touching saved preferences, set `DEFAULT_UI_THEME=classic` instead of running this.
