/* Terminal — the instrument panel.
 *
 * The rest of alphapinelab.com is light, airy and Apple-adjacent. This page
 * deliberately is not. A trading terminal earns trust through density: hairline
 * rules instead of cards, monospaced tabular figures instead of a display face,
 * uppercase micro-labels, and a dark ground so that colour means something
 * rather than decorating. The dark shell sits inside the ordinary site chrome,
 * which is what makes it read as an instrument rather than a different website.
 *
 * Colour carries exactly three meanings and never more:
 *   green   the model reads bullish
 *   red     the model reads bearish
 *   amber   caution — thin sample, stale data, a gate that is not satisfied
 * Everything else is neutral. Anything the model cannot support is rendered in
 * the muted tone with an em dash, never as a confident zero.
 */

/* Both themes are defined as the same token set, so every rule below — and the
   canvas, which reads these same custom properties at draw time — is written
   once and themed once. Adding a third theme would mean adding one block here
   and nothing else.

   The text ramp carries three steps and only three: `text` for values, `muted`
   for the labels that name them, `faint` for units and qualifiers. Each step is
   held above 4.5:1 against its own ground so the 9px micro-labels stay legible
   rather than merely present, which is where the first dark pass fell short. */
