src/lib/providers.ts holds a per-provider spec (url, headers, body,
extractor, default model) and a single callProvider() covering both the
action-prompt and custom-prompt families (~250 lines -> one path).
getSystemPrompt, fetchWithTimeout, and listModels move along with it;
background.ts drops from 553 to 130 lines.
Behavior pinned by 20 parity tests written from the old functions
(request shapes, headers, defaults, error strings). One deliberate
change: max_tokens now scales with input length (1024-8192) instead of
a hard-coded 1024, so Expand no longer truncates long selections.

Encrypt (Options) and decrypt (background) now share one module; wire
format unchanged. Tests include fixtures proving values encrypted by the
old inline Options code still decrypt, plus tamper/wrong-key cases. The
module documents the honest threat model (key co-located with ciphertext
= obfuscation, not encryption).

- src/lib/types.ts: message contract (both ANALYZE_TEXT shapes preserved),
config/response types, storage-key constants.
- src/lib/messaging.ts: single safeStorageGet/safeStorageSet/safeSendMessage/
isExtensionValid implementation replacing the three divergent copies in
Options, Popup, and content. Content script keeps its refresh-toast
behavior via an onContextInvalidated callback.
- New '@lib' import alias (wxt force-overwrites '~' and '@' to srcDir, so
those cannot point at ./src); wired in wxt.config, tsconfig, vitest.
- tests/unit/messaging.test.ts: 14 unit tests over the wrappers.
