Recorded in plan/fase-5-mobile-ux.md (new §5.14 with the six UX answers)
and CLAUDE.md "Fase 5 — what has been built" section. Also corrected the
"Fase 2a — what has been built" line that still claimed a sticky create
input for /lists, which was replaced by the masthead "New list" button
back in Fase 5.8.
Code change was committed in 3a11914.
