"""Brand single source of truth — name, domain, palette, fonts.

The product is **Read the Markets** (read.markets). "Cassandra" remains
the in-product *AI persona* (system prompt + chat label) — distinct from
the brand, the way Slackbot is distinct from Slack. Anything that crosses
into user-visible chrome (page titles, email headers, OpenRouter referer)
must read `BRAND_NAME` from here; do not hard-code the string.

Internal identifiers (`cassandra_session` cookie, pyproject package name,
SQLAlchemy GET_LOCK keys, file `cassandra.css`, env var `CASSANDRA_TOKEN`)
keep the legacy name on purpose — renaming them would invalidate live
sessions / advisory locks / configs for zero brand benefit.

The colour palette below is hand-authored in CSS as well; a drift-
detection test (`tests/test_branding_consistency.py`) parses
`cassandra.css` and asserts every variable matches. Update both or
neither.

The light theme is the *default* in emails — mail clients can't read
`localStorage`, so we can't replicate the dashboard's user-toggled
theme. Clients that honour `prefers-color-scheme` get the dark palette
via media query.
