/*
 * Document Card component -- production styles.
 *
 * Per Product Design System §5.7:
 *   - Desktop: grid of 2 columns within the reading column (or single
 *     column if descriptions are long -- a content-dependent judgement
 *     left to the composing page's grid container, not this card).
 *   - Tablet: single column.
 *   - Mobile: single column, full width.
 * This component only styles ONE card; the grid/column layout is the
 * composing page/container's responsibility (per the "consistent card
 * width regardless of value length" pattern already established for
 * Key Facts) -- so there is no @media rule here for column count, only
 * internal spacing, which does not differ by breakpoint.
 *
 * Structural spacing references only the resolved Stage 2 spacing
 * tokens and the resolved radius token. Colour remains pending-design-
 * signoff -- no colour value is set below.
