Splits the 2571-line cassandra.css into ten focused stylesheets: tokens (palette + fonts), layout (chrome), panels, dashboard, portfolio, log-chat, auth, settings, news, public. base.html and public_base.html load only what they need; auth pages (login, verify, unsubscribe confirm) load tokens + layout + auth. Brand drift-detection test repointed at tokens.css (where the palette now lives). 291 tests still pass.

"""Drift-detection: brand palette in `app/branding.py` must match the CSS.

|
|
Both the website (tokens.css) and the email templates use the same
|
|
palette. The CSS hand-authors the values in :root and [data-theme="light"]
|
|
blocks; this test parses those blocks and asserts every variable matches
|
|
its counterpart in branding.py. If a colour changes, both must change.
