It introduces a new `RouteContext` abstraction with a dedicated routing module, exports it for use across the HTML layer, and adds a detailed engineering plan documenting the intended `ItemId`/routing refactor, migration phases, risks, and testing strategy. While much of the added content is documentation, it also includes reusable code that establishes a new API for route generation. Commit A is a small cleanup that removes a UI preview section from a template, which is a much narrower change with limited architectural impact.\"}","refusal":null,"reasoning":null,"reasoning_details":[{"type":"reasoning.encrypted","data":"gAAAAABqXCQlKTFB36dUmFrsbYulijY6sw85jXaRwkrVKdNizUhgy6wU8XKXMvgYn_RI0CzIB9CjwpFV86_mIZ-snK76hczyB5xV2to3mn-Y5BBnPyE3HHVbWDex5C6ukEtu2YqztD0uUE5pcF2CAkw9AdP_gWlhQTnR7IJ2evLJT3qKjHjYVFO1tGILCtQxw0zBrvily8aV-5IjuRwOpmwZH52Riq6_sdvCyq2EBBESbR4YDSBJ59Cd_zgvy-CTrT__3_0Wl41ezX_qtDRREFXtL0lvZeiuJ3h9cbf3-8LktvZt4OtbM3hrKEGM63sT_PCD2k_vjVWgoRp3PUMAd-pfw25DLmZtyiokkFU9279_itvetMYEEze_t_a8WgHFxjUtBUCft3Y4WHByEEi7nYFjSIZmstSCn9IGS6JRHiEs7NgUE7A3qAb7OZyLkfBvQ4z_4BCfABm_YUPaoWOsAlKHpet3ICMq-1rBlvINGYQ_4IKTVIi1tvgVg4CUu5Fif8NzPbcZUVJ9zzKlAYd4GmoRrIQyoT-24uRCNWvn2wY--DlRH_80AGax_hJtuuAhaRTVkv3w1VjiJ7uVhO9tCIDEWQAq1g-Ww0Hjj7v-t4kW8gUrSkzsB8aAPEIzce6sJ83lRBOyDKY-3LkBLFU1KZajL3aaKrOGIEdJCMFHAS2PFUgCJiaQK8n75FWMR1krEpr4KkqoseQ-lDpnlkr7Hk0DsO6Ef9iXD_LOj2FRFSaE-CsnR3_IUBPbyt1wn86WBzyL7j4WNJ8HtFw8ifw3heFW8GrIKOata7zGIALoQqRRqo5EuYw3zo08xQ7y5RJ3KtGXfKiuOuuk49fyLU6MzZZlkJapSeGq6KaMVEJhxszMQGmWe5GlupSg8OCVvjT7ddmPfnTiaeICMvYJX_o9w_TjUJxHiuqCLW9C8Jvs1ALenQIwaOiJIUdaawpD8ZY_ljz7Y5xOwQs2M_GAYvB9mOj1tthK9MlxbLlUm5sRl_1PGlXNmnz_ij6XwHhcLi0zeBrCmlRJqlxD077zMPNkF8yO8j4FLoQOtXgR-P6HXxeQg8MFNLHP9vO3kKjCQOogiSRsW2eeZXJo","format":"openai-responses-v1","id":"rs_09de411264cf5e72016a5c2425671c819399593a217b60a959","index":0}]}}],"usage":{"prompt_tokens":4623,"completion_tokens":156,"total_tokens":4779,"cost":0.027795,"is_byok":false,"prompt_tokens_details":{"cached_tokens":0,"cache_write_tokens":0,"audio_tokens":0,"video_tokens":0},"cost_details":{"upstream_inference_cost":0.027795,"upstream_inference_prompt_cost":0.023115,"upstream_inference_completions_cost":0.00468},"completion_tokens_details":{"reasoning_tokens":0,"image_tokens":0,"audio_tokens":0}}}
