Visual properties of a TUI cell (everything except the character).
A TuiStyle bundles foreground color, background color, and text attributes into a single value. Any property can be flagged as "ignored" so that it inherits from a lower layer when styles are merged via merged().
An ignored color is represented by Color::Ignored (an invalid Color). Attributes use a separate mask: bits set in the mask are defined by this style; bits not in the mask are inherited during merging.
