Adds support for rcParam 'font.superfamily', allowing users to define logical font groups (superfamilies) that span multiple genres like 'serif', 'sans', and 'mono'.

Each superfamily maps genre + weight + style to real font names using keys like 'bold-italic' or 'normal-normal'.

Font resolution uses genre from font.family and matches against the selected superfamily, trying exact and fallback variants in order of specificity to generality.

Superfamilies can be defined by name (preloaded registry) or passed as inline dicts in rcParams['font.superfamily'].

Legacy behavior is preserved unless superfamily is set. If set, genre-aware matching replaces generic family name.

Includes defaults for DejaVu, Noto, Liberation, and more.
