/* =========================================================================
   DECOHERENCE design tokens
   Source: assets/banner.png flat bg (#5C4C94) + assets/avatar.png cyan fill
   (#00C9E9). Palette carries the concept literally: violet = uncollapsed /
   pending state, cyan = collapsed / included state, white = the certainty
   both resolve into. No gradients in the flat brand mark; gradients are
   reserved for the terminal-glyph icon set per the STRUCTURE row.
   Type: JetBrains Mono (terminal body/UI) + IBM Plex Mono (display/headers).
   A duo, not a triple, on purpose: a terminal is one typeface family in
   real life, so two weights of "mono" is the deliberate ceiling, not a
   missed slot. Corner radius stays small (2-6px) throughout: a terminal
   window has near-square corners, not app-icon rounding.
