feat(product): add reusable Product Experience 2.0

Unify product details modules behind config-driven contracts so teams can
extend UX without changing runtime architecture or bootstrap flow.

Keep backward compatibility with existing product payloads by treating new
media/specification/variant/related structures as optional extensions.

Improve conversion and content discoverability with reusable actions,
typed media rendering, grouped specifications, dynamic variants, and
multi-collection related products.

 ## Stop Point
 
 Product Details Module implementation is complete for Sprint 6. Stop here for approval before starting any further module work.
+
+## Sprint 11 - Product Experience 2.0
+
+Sprint 11 extends Product Details UX with reusable modules and config-driven behavior. Architecture, Widget Manifest, Section Engine, bootstrap loading, authentication, and payment logic remain unchanged.
+
+### New Reusable Modules
+
+- Product Actions module
+	- `Add to Cart`, `Buy Now`, `Wishlist`, `Compare`, `Share`, `Notify Me`
+	- `productPage.actions` controls visibility of each action
+- Product Gallery upgrade
+	- Media renderer by type (`image`, `video`, `pdf`, `manual`, `warranty`)
+	- Thumbnail strip + active media
+	- Mobile swipe support
+	- Zoom/fullscreen extension events (`zoomRequested`, `fullscreenRequested`)
+- Product Specifications upgrade
+	- Grouped attributes via `specificationGroups`
+	- Translated labels via `labels` map
+	- Backward-compatible fallback to `descriptionFields` and `attributes`
+- Variant Selector upgrade
+	- Dynamic option groups via `variantOptions`
+	- No hardcoded variant keys required
+	- Backward-compatible color/size fallback
+- Reviews upgrade
+	- Existing pagination preserved
+	- Optional `load-more` mode added via config
+	- Review form adds explicit validation and success state
+- Questions & Answers upgrade
+	- Existing list/answers/accepted-answer behavior preserved
+	- Submission can be toggled off while component remains future-ready
+- Related Products upgrade
+	- Supports multiple backend-provided collections
+	- Falls back to previous single related collection behavior
+
+### Config Additions (backward-compatible)
+
+`productPage` supports new optional keys:
+
+```json
+{
+	"reviews": {
+		"mode": "pages"
+	},
+	"questions": {
+		"allowSubmission": true
+	},
+	"actions": {
+		"enabled": true,
+		"addToCart": true,
+		"buyNow": true,
+		"wishlist": true,
+		"compare": true,
+		"share": true,
+		"notifyMe": true
+	}
+}
+```
+
+### Product JSON Extension Example
+
+```json

+	"variantOptions": [
+		{
+			"key": "storage",
+			"label": "Storage",
+			"options": [
+				{ "value": "256GB" },
+				{ "value": "512GB" }
+			]
+		}
+	],
+	"relatedCollections": [
+		{
+			"id": "frequently-bought-together",
+			"title": "Frequently bought together",
+			"titles": { "ru": "Покупают вместе", "hy": "Հաճախ գնում են միասին" },
+			"products": [9021, 9022, 9023]

+		{
+			"id": "similar-products",
+			"title": "Similar products",
+			"products": [9030, 9031]
+		}
+	]
+}
+```
+
+### Extension Points
+
+- Gallery overlays can subscribe to `zoomRequested` and `fullscreenRequested` without changing gallery internals.
+- Variant logic can add new option groups from backend by extending `variantOptions` only.
+- Specifications can add locale labels without frontend refactor.
+- Related collections can add campaign-specific blocks without changing section engine.
+- Action visibility and review mode can be tuned from config without component rewrites.
