The starter prompts displayed to the user before a chat begins are configured in prompts.ts.

To update the prompts:

1. Open data/prompts.ts.
2. Modify the STARTER_PROMPTS array.
3. Add, remove, or edit the strings as needed.

Example:

export const STARTER_PROMPTS = [
  "New prompt 1",
  "New prompt 2",
];

The weekly sustainability questions are configured in weekly-questions.ts.

Each entry in the WEEKLY_QUESTIONS array contains:

• week / publishDate — scheduling info
• question — the question shown to users
• answer — structured answer with value, unit, and optional secondary text
• explanation — markdown explanation (2–3 paragraphs)
• sources — list of references
• nextWeekTeaser — teaser for the following week's question
• meta (optional) — raw numbers behind the calculations

To add a new weekly question, append an entry to the array in data/weekly-questions.ts.

The backend assistant system prompt is managed in Langfuse Prompt Management.

• Prompt name is configured with LANGFUSE_SYSTEM_PROMPT_NAME.
• Optionally fetch by label with LANGFUSE_SYSTEM_PROMPT_LABEL.
• Optionally pin a specific version via LANGFUSE_SYSTEM_PROMPT_VERSION.
• If Langfuse prompt retrieval fails, the backend falls back to a local default system prompt so chat still works.
