a (#39)

* Fix dropdown option contrast in native menus

Set explicit option and optgroup colors so dropdown items remain readable in light native popups while keeping dark themed select controls.

* Fix manifest syntax and stale cache handling

Simplify the web manifest to a strict, minimal valid payload and add an app id. Bump service worker cache version and only cache successful network responses to prevent stale HTML/error responses from breaking manifest parsing.

* Prevent manifest challenge pages from polluting SW cache

Exclude manifest requests from service worker handling, remove manifest from app-shell precache, and avoid caching HTML for non-document requests. Bump cache version to flush previously cached bad responses.

* Update service-worker.js
