Graham McIntire e97748437c build(assets): split coverage hooks into a lazy-loaded chunk ... Switch esbuild to ESM with --splitting and load app.js as type=module. Heavy hooks now ship in their own chunk and only download when their LiveView mounts. - assets/js/lib/leaflet.ts: extract ensureLeaflet (vendored Leaflet loader) into a shared module with a typed window.L declaration. - assets/js/hooks/coverage_hooks.ts: extract CoverageMap, MultiCoverageMap, and CoverageLocationPicker (~510 lines) with proper interface types for hook context and tightened typing on payloads / event handlers (CoveragePayload is now a real type). - app.ts: replace those three inline hook bodies with lazyHook stubs that call import('./hooks/coverage_hooks') on first mount, forwarding lifecycle hooks once the chunk resolves. Also adds a scoped `declare const L: any` so the remaining Leaflet hooks type-check. - root.html.heex: switch the script tag to type=module so the emitted ESM bundle can use dynamic import(). - esbuild config: add --splitting --format=esm. Build output now produces: app.js 1.2 MB coverage_hooks-<hash>.js 16 KB (lazy) chunk-<hash>.js 2.4 KB (shared, lazy)		2026-05-06 16:11:32 -05:00
