Subject: [PATCH 01/10] refactor(confighttp): HTML page handlers into generic
 getPage function

Consolidated multiple individual HTML page handler functions into a single getPage function that serves different HTML files based on parameters. Updated server route bindings to use the new generic handler, reducing code duplication and improving maintainability.

Subject: [PATCH 02/10] Refactor handler signatures and server route setup

Updated all HTTP handler functions to take const reference parameters for response and request objects, improving const-correctness and clarity. Introduced a helper for page handlers and refactored server route setup to use concise lambda expressions and handler typedefs, reducing code duplication and improving maintainability.

Subject: [PATCH 03/10] Enforce empty request body for specific endpoints

Introduced check_request_body_empty to validate that certain API endpoints receive no request body, replacing previous content-type checks where appropriate. This improves request validation and ensures correct client usage for endpoints that do not expect a body.

Subject: [PATCH 05/10] Fix code example generation for optional JSON body

Refactors the generateExamples function to only include Content-Type headers and body parameters in cURL, JavaScript, and PowerShell examples when a request body is present. This prevents unnecessary headers and parameters in generated code samples for endpoints that do not require a body.

Subject: [PATCH 06/10] Add HTTPS confighttp tests and update API

Add initial unit tests for confighttp using a real HTTPS client/server (tests/unit/test_confighttp.cpp). Update confighttp public API and types: add necessary includes (nlohmann::json, Simple-Web-Server), introduce HTTPS type aliases (https_server_t, resp_https_t, req_https_t), and declare helper functions (print_req, send_response, send_unauthorized, send_redirect, authenticate, not_found, bad_request, check_* utilities, getPage, etc.). Align implementations in src/confighttp.cpp with the header by removing default parameters from not_found, bad_request, and getPage signatures. These changes improve test coverage and clarify the confighttp interface.

Subject: [PATCH 07/10] Suppress GCC warnings in tests_common.h

Wrap test header includes with #pragma GCC diagnostic push/pop to ignore -Warray-bounds and -Wstringop-overflow on GCC (excluding clang). This suppresses known false-positive warnings originating from Boost.Asio's basic_resolver_results.hpp on some GCC versions (notably observed on Arch Linux) and restores diagnostics after the includes.

Subject: [PATCH 08/10] Rename getNodeModules to getAsset; add tests

Rename confighttp::getNodeModules to confighttp::getAsset and update the server resource mapping. Add function declarations for getAsset and getLocale to confighttp.h. Expand unit tests (tests/unit/test_confighttp.cpp): include iostream, persist/restore locale in setup/teardown, create a test HTML file in WEB_DIR, register multiple test routes exercising send_response, send_redirect, check_content_type, check_request_body_empty, getPage, and getLocale, and add many corresponding test cases to improve coverage and validate headers, content types, redirects, auth behavior, and JSON responses.

Subject: [PATCH 09/10] Use writable test assets dir; simplify setup

Override SUNSHINE_ASSETS_DIR in tests to ${CMAKE_CURRENT_BINARY_DIR}/test_assets so tests use a writable assets directory. Update test_confighttp setup to create a temporary web directory, use std::filesystem::create_directories for WEB_DIR, and write test_page.html directly (removing the previous try/catch and existence checks). These changes simplify test setup and ensure test files are created in writable temp locations.

Subject: [PATCH 10/10] Add CSRF protection and token endpoint

Implement CSRF protection across HTTP API endpoints and expose a token endpoint. Changes include:

- Add docs: API and configuration docs updated to describe CSRF protection and the new GET /api/csrf-token endpoint.
- Config: add csrf_allowed_origins to config struct; parse comma-separated origin lists; include built-in localhost defaults and append web UI port-specific origins once port is known.
- confighttp: implement CSRF token generation, storage (with expiration), client identification, and validation logic. Validation allows same-origin requests via Origin/Referer to bypass tokens and requires X-CSRF-Token header or csrf_token query param for cross-origin requests. Register GET /api/csrf-token and integrate validation into state-changing endpoints.
- Web UI: add form field and localization strings for csrf_allowed_origins and include it in config HTML.
- Tests: add unit tests for CSRF token generation, header/query validation, same-origin exemptions, and restore/cleanup of config state.

Also remove usages of the old empty-body checker where CSRF/authentication flow was applied. This commit wires CSRF protection end-to-end (docs, config, server, UI, and tests).

+## CSRF Protection
+
+State-changing API endpoints (POST, DELETE) are protected against Cross-Site Request Forgery (CSRF) attacks.
+
+**For Web Browsers:**
+- Requests from same-origin (configured via `csrf_allowed_origins`) are automatically allowed
+- Cross-origin requests require a CSRF token
+
+**For Non-Browser Applications:**
+- Applications making requests from the same origin configured in `csrf_allowed_origins` do NOT need CSRF tokens
+- The `Origin` or `Referer` header is automatically checked
+- If your application is making requests from a different origin, you need to:
+  1. Get a CSRF token from `GET /api/csrf-token`
+  2. Include it in requests via `X-CSRF-Token` header or `csrf_token` query parameter
+
+**Example:**
+```bash
+# Get CSRF token (if needed)
+curl -u user:pass https://localhost:47990/api/csrf-token
+
+# Use token in request
+curl -u user:pass -H "X-CSRF-Token: your_token_here" \
+  -X POST https://localhost:47990/api/restart
+```
