Make my {{tech_stack}} site available in {{languages}}. Read the existing code first and show me a short plan before changing files. Structure: - Each language gets its own URL path, with the default language at the root - The correct language attribute on every page - A switcher that names each language in itself, such as Español, without flags, keeping visitors on the same page - Remember the visitor's choice; suggest a language from browser settings with a dismissible note, but never force a redirect Text and content: - Every interface string moved into one message file per language, using the i18n library that suits my stack - Plurals and variables handled by the library, never by joining strings - Dates, numbers and prices formatted for each locale - For database content, propose how to store translations, falling back to the default language when one is missing Search: - Translated page titles, meta descriptions and share tags - Hreflang links between every version of each page, plus x-default, and every language in the sitemap Leave room for text that runs 30 percent longer, and support right-to-left layout if any language needs it. When you're done, list the files changed, the strings still to translate, and anything you assumed.
