Project updates from Template

This commit contains the latest updates from the generic Website template, which rework the compression and localization:

- Reworked the compression and localization in the Infrastructure package. (3c568e4)
- Adopted the reworked compression and localization in the Website service. (08cf3e3)

The template commit that only touched the root README (53676ed) was left out, as this project no longer carries that file.

 ## Overview
 | Role | Types |
 | --- | --- |
 | Routing | `RouterController`, `RouteCollectionBuilder`, the `addController` extension on `RouterMethods` |
-| Middlewares | `SecurityHeadersMiddleware`, `HTTPSRedirectMiddleware`, `TrailingSlashRedirectMiddleware`, `VaryMiddleware`, `RateLimitMiddleware`, `LocalizationMiddleware` (negotiating from a `lang` query parameter, then a leading path segment, then `Accept-Language`), `NotFoundMiddleware` |
+| Middlewares | `SecurityHeadersMiddleware`, `HTTPSRedirectMiddleware`, `TrailingSlashRedirectMiddleware`, `VaryMiddleware`, `CompressionMiddleware`, `RateLimitMiddleware`, `NotFoundMiddleware` |
 | Pages and assets | `Page`, `Asset`, `AssetExtension`, `FingerprintAssets` |
 | Link previews | `SocialCard`, its `locale` and the `alternateLocales` of its other language editions, its `Image` and `Style`, and the `Tag` meta tags it derives |
 | Structured data | `StructuredData`, the `Node`, `Property`, and `Value` types of its schema.org graph, the open `Name` and `Kind` vocabularies, and the site-wide initializer building the `Organization`/`WebSite` pair |
 | Analytics | `Analytics`, the `Event`s a page reports (with `tagging()` to apply one to any attribute-bearing HTML or SVG tag), the tracker script `Attribute`s it derives, the optional session `recorder` script paired with it, and the `origin` its preconnect hint targets |
-| Responses | `CachedHTMLResponse`, and `LocalizedHTMLCollectionResponse` rendering one of them per catalog language |
-| Contexts | `LocalizedRequestContext` |
+| Responses | `CachedHTMLResponse` (rendered and gzipped once), `LocalizedHTMLCollectionResponse` (one of those per language) |
+| Localization | The `Negotiate` extension resolving a request's language from its `lang` override, path prefix, and `Accept-Language` |
 | Constants | The `HTTPField.Name` header names, `Int.RateLimit` limits, and `String.Security` header values the middlewares default to |
 
 ## Design rules
@@ -21,6 +21,8 @@ The package holds only what every service can reuse. Anything a service owns is
 - **Nodes are joined by `@id`, not repetition.** A node another page must point at gets its identifier from a helper rather than a hand-spelled fragment — `organizationID(forSiteURL:)` names the node the site-wide initializer builds, and that initializer's `founder` takes such an identifier back. A service adds the helper for any node it owns, so neither side can drift.
 - **Services fill the gaps once, via extensions.** A service restores its convenient call sites retroactively — the Website's `*+Defaults` are the pattern. The open schema.org vocabularies work the same way: the package declares the shared `Property.Name` and `Node.Kind` constants, a service adds its own.
 - **Method structs.** Single-operation types such as `FingerprintAssets` take lifetime-fixed configuration in `init` and per-call inputs in `callAsFunction`.
+- **Wrap upstream, do not restate it.** Where a Hummingbird middleware is almost right, the package delegates to it and adds only the missing decision — `CompressionMiddleware` passes everything to `ResponseCompressionMiddleware` except responses that already name an encoding, which it would otherwise compress twice.
+- **Ask where the answer is used.** Work every request pays for must be work every request needs. The request's language is negotiated by the responders that read it, not stamped onto a context on the way past.

 - Swift 6.3 toolchain (`swift-tools-version:6.3`).
 - macOS 15, matching the sibling packages. The services deploy to Linux containers; the packages declare no UI platforms.
