fix(layout): fit names on phones without sideways scroll

Display and game names shrink to 0.875rem, then end with an ellipsis
(FitText + fit-text utility, CSS container units, full text in title).
Rows and buttons wrap at large fonts, header points chip can shrink.
Guard: scripts/check-overflow.js.
