Core Elm-architecture implementation on top of Replicant for Clojure/ClojureScript.

Provides:
- Component lifecycle management (`component`, `render`) with isolated local states
- Global application context shared across all components
- Message-based state updates via the `update` multimethod
- Side-effect handling via the `fx` multimethod
- Centralized message dispatching (`dispatch`) integrated with Replicant DOM events

HTTP side-effect module for Relm built on the Fetch API.

Provides `core/fx` side effects for making asynchronous HTTP requests (`::fetch`)
and aborting active requests (`::abort`). Handles JSON serialization, query parameter
encoding, response header parsing, response body decoding based on Content-Type,
request timeouts, and error handling with automated message dispatching back into Relm.

Browser navigation and History API side effects for Relm applications.

Provides `core/fx` implementations for browser navigation actions:
- `::navigate-to!`   Navigate to a new URL via `location.assign`
- `::replace!`       Replace current URL without adding a history entry via `location.replace`
- `::reload!`        Reload current page via `location.reload`
- `::back!`          Move back one step in browser history via `history.back`
- `::push-state!`    Push a new entry onto browser history stack via `history.pushState`
- `::replace-state!` Replace current history entry via `history.replaceState`
- `::go!`            Navigate by relative delta `n` via `history.go`
