Render maps at natural resolution inside a CSS-transform world layer (zoom,
pan, fit-to-view) instead of shrinking to maxWidth — large maps are now usable.

places party PCs / active-encounter combatants / blanks in one click with dup
detection; tokens gain optional combatantId (Dexie v9) for live encounter HP.
