 * Semantic surfaces — the radius/elevation scale, applied.
 * ---------------------------------------------------------------------------
 * Use ONE of these instead of hand-assembling `bg-white rounded-xl shadow`.
 * Which one you pick is a statement about HIERARCHY, so pick by what the thing
 * IS, not by what looks nice in isolation:
 *
 *   .surface-tile     a stat / KPI tile — a small peer in a row or grid.
 *                     WHITE when it sits on the canvas, a grey FILL when it sits
 *                     inside a white surface. Never a border, never a shadow.
 *   .surface-card     the primary content surface — a panel wrapping a chart,
 *                     a table, or a titled section. Flat white, large corners.
 *   .surface-popover  a dropdown, tooltip body, or menu — transient, above the
 *                     page but not blocking it. The first surface with a shadow.
 *   .surface-overlay  a modal, dialog, or slide-over — blocks the page; pair it
 *                     with a .scrim behind it.
 *
 * NO BORDERS, NO RESTING SHADOWS (2026-10 refresh). Separation comes from tone:
 * white on the grey canvas, grey fill on white. A hairline or a shadow on top of
 * a tone step is noise. Only what floats (popover, overlay) casts a shadow.
 *
 * CHARTS STAY ON WHITE. The chart palettes are validated against white, so a
 * surface that holds a <canvas> is never given the grey fill: a card nested in
 * a card that holds a chart keeps white and takes an inset hairline instead.
 *
 * Radius tracks hierarchy: 14px control -> 20px tile -> 24px card -> 28px overlay.
 *
 * LOAD-ORDER TRAP, measured 2026-08-19 — READ THIS BEFORE USING THESE CLASSES.
 * Tailwind is loaded from the CDN and injects its utilities into the document
 * AFTER this stylesheet. Tailwind utilities and these classes are both
 * single-class selectors, so they have EQUAL specificity and the later one wins:
 * Tailwind's. Verified live — an element with `class="surface-card rounded-xl
 * shadow"` computes Tailwind's radius, not the token.
 *
 * Consequence: you MUST DELETE the conflicting utilities (rounded-*, shadow-*,
 * bg-white, and any border-gray-*) when you apply a surface class. Adding the
 * class on top of them does nothing and FAILS SILENTLY.
 *
 * Do NOT "solve" this by doubling the selector (.surface-card.surface-card) or
 * with !important. Delete the utilities, then verify by reading COMPUTED style.
