/* Reconbrief — structural stylesheet.
 *
 * All component styling lives here and references CSS custom properties.
 * A theme (static/themes/<name>.css, chosen by viewer.theme in domain.yaml)
 * only re-declares those variables — and, where a theme wants a different
 * layout, overrides a handful of rules. This keeps "add a new look" to a
 * ~30-line file instead of a template fork.
 *
 * The variable defaults below are a neutral light theme, so the viewer is
 * presentable even if a theme file fails to load. */
