Matt 35e2921615 feat(map): Add state/province boundary lines at z4-z7 ... Fix D: State and province administrative boundaries are now visible at low zoom levels (z4-z7) with theme-aware styling. - Added STATE_BOUNDARIES_LAYER constant - Added addStateBoundaries() function that creates a line layer filtering on kind_detail = 4 (state/province level) - Uses dashed line style with opacity interpolation - Layer uses theme boundaries color for consistency - Layer is re-added on theme change to update colors The layer renders below labels and provides subtle but visible state/province boundaries when zoomed out viewing country-level maps. Line width and opacity increase as you zoom in from z4 to z7. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>		2026-05-02 19:06:33 +00:00
