- Dynamic name fields (3–6 players) with add/remove controls
- Start button disabled until all names are non-blank and unique;
uniqueness check normalizes internal whitespace so "Bob Smith"
and "Bob Smith" are treated as the same name
- Names passed to game state are edge-trimmed only, preserving
internal spacing as the user typed it
- Failing fields highlighted with red border and light red background
- PrimaryButton gains disabled prop with faded/flat appearance;
active press state suppressed when disabled
- All round buttons now use consistent shadow and translateY values

- PageFrame: parchment-background frame with title, diamond-rule divider,
scrollable content area, and optional bottom-pinned footer slot
- PrimaryButton: shared full-width button (light blue, drop shadow, pressed
state via translateY + shadow reduction) — used by TitleScreen and PlayerSetup
- Global button base in index.css ensures touch-friendly sizing everywhere
- TitleScreen consolidated to use PrimaryButton instead of its own button style
