"""Drop the legacy `billboard-` slug prefix from billboard applets and
|
||
|
|
rename Most Recent → Most Recent Scroll.
|
||
|
|
|
||
|
|
The `billboard-` prefix snuck into seed migration 0003 against intent — no
|
||
|
|
other context (dashboard, gameboard, wallet, game-kit) prefixes its applet
|
||
|
|
slugs with the context name, and slugs need to stay portable so users can
|
||
|
|
later rearrange which page hosts which applet.
