- Add CSS variables (--cell, --cell-font, --trigger-h) for responsive cell sizing
- Shrink grid cells at 600px and 420px breakpoints
- Add .page-body wrapper with 16px horizontal padding to prevent edge collisions
- Separate hint column from scrollable grid: hints rendered outside the table in a fixed flex column, only the letter grid scrolls horizontally

Display spaces, hyphens and other non-letter characters as static cells
instead of input fields, and add separator rows in the grid for
non-alphabetic characters in the main actor's name.
