    Codex Profiles to separate personal and work token consumption from OpenAI

These notes are a work in process to help create some structure around separating token consumption for personal explorations from work related tasks.
The assumption is that the token budget is handled separately from either.

Personal access - uses an OpenAI personal subscription
Work access - uses an API key

Approach

The simple approach is to allow the "default" mode of invoking codex to use the personal subscription which has been logged in with oauth.
Then create a new codex profile and use that with the API key in the environment.

    Why olm.package.icon matters for OperatorHub tiles on olm.csv.metadata bundles

Context: RHWA-1093 / RHWA-1190 — investigating why RHWA operators show the default gray lightning bolt icon in the Software Catalog even though the bundle CSV's spec.icon is present and correct.
Code refs are from openshift/operator-framework-olm release-4.22 and openshift/console main.

The two icon paths in the console
