/* Filing Signals — a register, not an essay.
   Deliberately NOT an editorial-serif layout: monospace carries the metadata,
   the palette is cool slate rather than warm paper, corners are square and the
   structure is ruled and dense. Colour is reserved almost entirely for data
   encoding; the one status colour is used only for severity.
   Series slots are the validated categorical set (see charts.py) and are fixed,
   so a signal keeps its colour in tags, row rules and charts alike. */
