 * Editorial cartographic section. Matches the existing .card pattern
 * (white bg, 20px radius, flame top bar) but layers a faint topographic
 * background, runs subtle contour lines through the data bars, and
 * inscribes the dominant percentages directly inside the textured
 * segments using DM Serif Display italic.
 *
 * Reuses the surface textures from the admin terrain module but with a
 * slightly more saturated public palette + larger bar heights (72px
 * surface / 56px highway on desktop) for an editorial weight.
