**Done, 2026-08-06.** `.payment-modal`/`.bank-payment-modal` on the cart page now render through the shared `app-dialog` primitive instead of hand-rolled overlays. Two earlier same-session attempts were reverted before landing (one stopped cleanly after finding real conflicts, one botched the sequencing — deleted the old focus-trap before finishing the swap); this pass fixed the actual API gaps first, then migrated, then verified live in a browser before shipping:
-`DialogComponent` gained `closeOnEscape`/`closeOnBackdropClick` inputs (default `true`, backward-compatible with its other 13 call sites) and an `ariaLabel` input (for dialogs with no visible title header — cart's modals render their own close button in content instead). `FOCUSABLE_SELECTOR` now includes `iframe` (needed for the bank-payment panel's focus trap).
- Cart wires `[closeOnBackdropClick]="false"` on both dialogs (in-flight payment shouldn't cancel on a stray click) and `[closeOnEscape]="!showBankPaymentPopup()"` on the QR/status dialog (so Escape closes the bank iframe first, falls back to the QR view, matches the original nested-modal priority).
- Exact original geometry (500px QR modal, 40px padding; 960×760 bank iframe modal, 56/16/16 padding, both mobile breakpoints) preserved via `:host ::ng-deep` overrides on `.app-dialog-panel`/`.app-dialog-panel__body`/`.app-dialog-backdrop`, scoped per-instance via `.payment-dialog`/`.bank-payment-dialog` host classes — same `::ng-deep` pattern already used by `product-carousel-widget.component.ts`.
-`cart.component.ts` lost its hand-rolled `@ViewChild`/`@HostListener`/focus-trap methods (~90 lines) — `app-dialog` owns all of that now.
- Verified live: both dialogs render at correct size/padding/aria-label at mobile and desktop breakpoints, backdrop-click confirmed inert, Escape-priority confirmed (closes bank first, then QR), initial focus confirmed landing on the close button. 83/83 tests pass, tsc/build clean.
Researched, not executed. Estimated ~2–3.5 days, needs the `barry-cache` dependency fix and a Node version bump first. Explicitly out of scope for the Backend Finalization Sprint. Plan: `docs/ANGULAR22_PLAN.md`.
**Initial (eagerly-loaded) bundle carries an ~11 MB chunk that is the entire `@lucide/angular` icon set**, confirmed 2026-08-05 by inspecting build output — `app-icon`/`IconComponent` only ever needs the ~85 icons named in `icon-registry.ts`, but esbuild is not eliminating the other ~1500+ unused icon classes from `@lucide/angular`'s single-file `fesm2022/lucide-angular.mjs` bundle, despite the package declaring `sideEffects: false` and every usage in this codebase being clean named imports (no wildcard imports found). Root cause not fully diagnosed — likely each icon's Angular component metadata assignment isn't PURE-annotated in that build, so esbuild can't drop unreferenced classes within the single shared module even though it can drop unreferenced *exports*. The package ships no per-icon deep-import path as a workaround (single fesm file only). Real fix options, neither attempted here (touches a dependency, needs sign-off): (a) check for a newer `@lucide/angular` release with better tree-shaking, (b) drop the dependency and hand-roll inline SVG path data for just the ~85 used icons (removes a dependency, matches this repo's minimal-deps convention, but is real work — extracting/verifying 85 icon paths). This alone is roughly **6x the size of the two lazy chunks below combined** and, unlike them, ships to every visitor on first load.
Two lazy chunks are also large: `project-editor` (~1.0 MB), `catalog-container` (~330–375 kB, varies by build). No mechanical split found yet for either — needs a dedicated profiling task, ideally under real backend latency per `docs/NEXT_PHASE.md` Phase 3.
A dead-space gap between the hero and categories section on the storefront home page traces to bootstrap mock config (widget/section padding values in the dev fixture), not a confirmed code defect. Needs reproduction with real tenant data before it's worth investigating further — not a bug until it's confirmed to happen outside the mock fixture.
