/* blocks.css — block visual rules for every CURRENT version, organized by catalog order (02 §5.1).
   Hard rule (02 §3): an existing class's meaning is never redefined. A new block version that
   looks different introduces new class names for what changed; old classes stay untouched for as
   long as any live tool_blocks row depends on them. Populated as block partials are built (Phase 1). */
