Element is replaced by two types: Behavior (a plain struct of runtime properties: passable, opaque) and Archetype (an enum of named presets: Empty, Wall, Object, ErrorBlock). Board.cells changes from Vec<(Glyph, usize)> to Vec<(Glyph, Archetype)>, eliminating the per-board element palette. Map files now reference archetypes by name (archetype = "wall") instead of property bags (passable = false), so the archetype list can be reordered without breaking saved games. Unknown archetype names produce an ErrorBlock cell (yellow ? on red) so malformed maps are immediately visible in-game. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
