Use common sans-serif fonts, labels at 15px or larger, solid orange arrows for
current flow, amber dashed arrows for evidence/provenance, and muted dashed
arrows for future routes. Do not rely on color alone: meaningful states also
need text and shape treatment. Keep explanations in MDX rather than placing
paragraphs inside a diagram.

Visual system
The reusable visual grammar for canonical state, providers, evidence, and future work.
PROJECT B.R.A.I.N. uses editable SVGs as its primary conceptual visual medium.
The visuals explain accepted architecture; they do not imply that deferred work
is implemented.
