/*
 * Dominion AI — "Simplify My Chat" (LANE I). A stripped-down CRT-terminal chat surface: one input,
 * the conversation, nothing else. Black background, neon outlines/text, scanlines and phosphor
 * glow, monospace restraint. No cartoonish shapes, no bounce, no confetti — CRT retro done straight.
 *
 * Layout is flexbox top-to-bottom on purpose: no CSS grid, no hard-coded column count anywhere in
 * this file (Fred's standing rule). Only `transform` and `opacity` are animated/transitioned.
 *
 * #simplify-root is appended directly to document.body (see dominion-simplify.js) specifically so
 * `position: fixed` here is never nested under an ancestor with transform/filter/will-change —
 * that combination silently breaks fixed positioning in this codebase (verified against
 * dominion-cinematic-01.css: body itself sets position:relative + isolation:isolate, neither of
 * which creates a fixed-position containing block; no transform/filter/will-change exists on body
 * in this app today).
 *
 * Two user controls only: line color and text color, both persisted (see dominion-simplify.js).
 * Everything else here reads those two CSS custom properties.
