  "_comment": "2026-08-07: enables 'Add to Home Screen' installability for purchase-planner.html (renamed from payment-explorer.html). Two things still needed before this actually does anything: (1) the page must be served over real HTTPS hosting at a stable domain — browsers ignore manifests on file:// or unpublished hosts; (2) real icon PNGs at the sizes below need to replace this placeholder reference (a simple Lumera 'L' mark on navy, 192x192 and 512x512, would satisfy Android/Chrome's install requirements). Once both are true, Chrome/Edge on Android will offer a native 'Install' prompt automatically; iOS Safari has no equivalent auto-prompt, which is why purchase-planner.html shows manual 'Add to Home Screen' instructions instead of relying on this manifest for iOS.",
