"""Cassandra brand palette — single source of truth.

Both the website's CSS (`app/static/css/cassandra.css`) and the email
templates (`app/services/email_service.py`) draw from these dicts. CSS
hand-authors the values in its `:root` / `[data-theme="light"]` blocks;
a drift-detection test (`tests/test_branding_consistency.py`) asserts
that what's in this module matches what's in the CSS, so updating the
brand in one place without the other fails CI.

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.
