docs: agree the visual-style plan

The mark was approved on its own sheet and the panel was left on the default
blue-on-cool-grey it shipped with, so the two read as different designs. Write
down what the panel takes from the proof — brick as the accent, warm paper,
IBM Plex self-hosted — and what it deliberately does not: the proof's mock puts
navigation in a dark top bar, which has nowhere to keep the per-page section
index the left column carries.

Records the decisions that cost something to reverse: three font files (76 KB)
served from the panel's own origin so the CSP stays default-src 'self', brick
split into a fill and a text value because #7A3B2E is unreadable as a link on
the dark scheme, and the test that outranks all of it — the accent must not be
mistakable for a status badge.
