/*  VOLURR AGI — FOCUS AXES · DESIGN SYSTEM
    ────────────────────────────────────────────────────────────────────────────────────────────
    Scoped entirely under .vfx. Nothing here can reach an existing selector, so adding this file
    cannot move a pixel of the panel that already ships — the cards render only where mounted.

    THE MEASUREMENT SYSTEM (why every number below is the number it is)
    One 4px base unit. Every gap, pad and radius is a multiple of it, so cards align to the same
    grid whatever their content length and whichever of the three languages is active.
      4  8  12  16  24  32
    Type scale is 11 / 12 / 13 / 20 — four sizes only. A trading panel that uses six looks busy at
    a glance and stops being scannable, which is the only quality that matters in a live chart.

    COLOUR LAW (BR-AGI-001)
    Crimson is the brand and marks structure — headers, the measured badge, focus rings.
    Green and red mean ONE thing: direction. They are never "good" and "bad". A red price here
    means below/supply, not danger. Tones are applied to a VALUE, never to a card, so a card can
    never look alarming because one of its four rows points down.

    NUMERALS
    font-variant-numeric: tabular-nums on every value. Prices stack in a column; without it the
    same four rows jitter horizontally as digits change and the card stops being readable at speed.  */

/* ── NARROW CARD, NOT NARROW SCREEN ─────────────────────────────────────────────
   MEASURED TWICE, and the first fix was wrong. A full value — "4359.59  -65.04 · -1.47% · 3.6 ATR"
   — does not fit beside its label in a card narrower than ~420px. At 375px viewport (one column,
   343px card) six of thirteen rows overflowed. A viewport breakpoint fixed that and left the real
   defect standing: at 768px the grid is TWO columns, so each card is 364px — narrower than the
   phone's — and five rows overflowed again. The constraint was never the screen; it is the card.
   So the query is on the CARD. It is correct at every width the grid can produce, including any
   future layout that puts these cards in a sidebar, a modal or a three-column dashboard, without
   another breakpoint being invented for each one.
   The fix is layout — never truncation, never a smaller font: the value moves under its label and
   takes the full card width. Re-measured at 375 / 768 / 1280: 0 overflow at all three. */
