/* Risk Watch encoding vocabulary.
 *
 * Every visual channel the dashboard uses is named here exactly once. Nothing
 * else in the stylesheets or the render code may introduce a colour: if a value
 * is not in this file it is not part of the vocabulary.
 *
 * The page is dark-only on purpose. It is an operator monitor rendered on one
 * surface, and the stress ramp and status steps below were validated against
 * that surface specifically.
 *
 * | Property         | Channel                                    |
 * | ---------------- | ------------------------------------------ |
 * | Stress magnitude | sequential ramp, one hue, --stress-0..5    |
 * | Score direction  | glyph + word, never colour alone           |
 * | Regime           | reserved status hues, always with a label  |
 * | Proxy vs direct  | hollow / dashed mark, never a hue          |
 * | Coverage         | partial fill (arc on scores, bar on rows)  |
 * | Unavailable      | --dim plus an explicit word, never 0.0     |
 * | Freshness        | opacity decayed against the signal window  |
 * | Parse confidence | mark border weight                         |
