- New layout prop with values 'inline' (default) and 'block-list-row'.
The block-list-row variant bakes in full-width, left-aligned content
with trailing icon and text-sm, replacing the ~10-class override
duplicated across FilterGroup, FontList, and similar list-row sites.
- primary variant's three hard-offset shadows now reference the
shadow-stamp-{rest,hover,pressed} tokens; the 0.0625rem translate
becomes translate-{x,y}-px.
- Base classes use text-label-mono and duration-normal utilities
instead of inline 'font-primary font-bold tracking-tight uppercase'
and 'duration-200'.
- The icon variant's background uses surface-canvas (semantic naming;
picks up dark-mode automatically via --color-surface).
- text-secondary → text-subtle (avoids collision with the @theme
--color-secondary token; see earlier styles commit).
New exported type: ButtonLayout.
