DRIFT v0.6.1

Fixed

• Made the FastAPI documentation banner frame follow prefers-color-scheme,
  so the light canonical banner no longer sits inside a dark wrapper.

• Made the frontend briefing state explicit: it now distinguishes a loading
  request, an unreachable API, and the intentional empty state before reviewed
  evidence has been published.

• Made the frontend select the API-served canonical DRIFT banner pair with
  prefers-color-scheme; it no longer copies SVGs into the Vercel build, and
  its palette follows the same light/dark system preference as the README and
  API docs.

• Corrected current local-test documentation to 142 tests at 100.00% backend
  coverage and replaced the placeholder clone URL.

Hosted deployment verification — 2026-07-16

• Verified the Git-connected Railway v0.6.1 deployment in DRIFT_MODE=live:
  /health reported v0.6.1, /briefing returned [] because no Insight is
  human-reviewed, /docs returned 200, and a Vercel-origin CORS preflight
  passed.
• Verified that the deployed Vercel HTML references the canonical API-served
  light/dark banner pair. This is source-markup verification, not a separate
  browser visual check of the post-fetch empty state.

Codex session record

• Added 019f6a46-e3eb-7de2-81b1-91515ae80043 for the submission audit and
  frontend evidence-presentation follow-up. Initiative 04 remains the primary
  /feedback session for core functionality.
