 ## Key conventions
 
-- All LLM prompts are in `src/prompts.ts`. Each report type has its own builder function. Prompts are written in Chinese and produce Chinese output.
+- All bilingual strings (titles, labels, footers, messages) are centralized in `src/i18n.ts`. Use the `Lang` type (`"zh" | "en"`) and `Record<Lang, string>` maps. Do not add inline bilingual ternaries elsewhere.
+- LLM prompt builders are split across two files: `src/prompts.ts` (repo-level prompts) and `src/prompts-data.ts` (data-source and rollup prompts). Each report type has its own builder function.
 - `callLlm(prompt, maxTokens?)` defaults to 4096 tokens. Web report uses 8192, trending uses 6144. HN report uses the default 4096.
 - On 429 rate-limit errors `callLlm` retries up to 3 times with exponential backoff (5 s / 10 s / 20 s); the concurrency slot is released during the wait.
-- The concurrency limiter (`LLM_CONCURRENCY = 5`) prevents 429s when many parallel LLM calls fire. Do not bypass it by calling the Anthropic SDK directly.
+- The concurrency limiter (`LLM_CONCURRENCY = 5`) prevents 429s when many parallel LLM calls fire. Do not bypass it by calling SDK clients directly.
+- LLM provider is selected via `LLM_PROVIDER` env var (default: `anthropic`). Valid values: `anthropic`, `openai`, `github-copilot`, `openrouter`.
+- Provider implementations live in `src/providers/`. Each file implements the `LlmProvider` interface. The factory in `src/providers/index.ts` validates the provider name and logs only the provider name — never API keys or endpoint URLs.
 - GitHub issue label colors are defined in `LABEL_COLORS` in `src/github.ts`. Add new labels there.
 - `sampleNote(total, sampled)` in `src/prompts.ts` formats the "(共 N 条，展示前 M 条)" note. Reuse it — do not inline the same string format.
 - Web state (`digests/web-state.json`) is committed to git on every run. It is the source of truth for which URLs have been seen.

 1. Create a data fetcher (or add to an existing one).
-2. Add a `buildXxxPrompt` function in `src/prompts.ts`.
-3. Wire into `fetchAllData`, `generateSummaries`, and a `saveXxxReport` function in `src/index.ts`.

-5. Add the report ID and label to `REPORT_LABELS` in `src/generate-manifest.ts` and `LABELS` in `index.html`.
