/* Providence control panel.
 *
 * This is an operator readout for a sweep that runs for weeks. The data is
 * addresses, ports, version strings and counts, so the type work is about
 * scanning a column, not personality: identifiers and numbers get a monospace
 * column so they line up, everything else is the system UI font. No webfonts,
 * because the binary embeds these files and serves them with no external
 * requests: the panel has to open instantly on a LAN box that might have no
 * route to a CDN.
 *
 * Dark by default because the thing gets glanced at from a terminal at odd
 * hours, but that's a decision not a costume, so the light theme is a full
 * theme and the toggle is remembered.
 *
 * Colour budget: two greys for structure, one green accent for "alive", amber
 * and red held back for state that needs attention. Nothing glows, nothing is
 * glass, radii are small and only one surface gets to cast a shadow.
 *
 * Dial: ENERGY 2 / RHYTHM 3 / MOTION 1.
 *   ENERGY 2 because the data leads and the chrome stays quiet, but the
 *   counters strip should be readable across a room.
 *   RHYTHM 3 because the panes are genuinely different shapes: a dense table, a
 *   profile picker over a long form, a name search, a log tail, an account list.
 *   MOTION 1 because a panel that runs for weeks should sit still. Hover and
 *   focus states only; the one movement is a new row arriving.
 *
 * Picked by the agent: there's no DESIGN.md behind them yet, so this is a
 * considered default rather than the product owner's. The monospace data column
 * and the green "alive" vocabulary are the motif.
