The fully-parsed, validated description of one FSL Markdown fence block.
Sizing semantics: width/height (from width=/height= tokens) are
exact dimensions — the host renders the block at that size.
max_width/max_height (from max-width=/max-height= tokens) are
upper bounds on natural sizing — the block renders at its natural size
but is capped on that axis. When both an exact and a max token are given
for the same axis, the exact dimension wins and the cap is moot. All four
are null when their token is absent.
