/**
 * Salud Medica brand theme — intentionally empty.
 *
 * SMX's palette is defined in src/index.css (:root and .dark blocks).
 * This file exists so the `<link rel="stylesheet" href="/brand-theme.css">`
 * in index.html resolves cleanly for the SMX build too; any actual
 * overrides for SMX belong in src/index.css, not here.
 *
 * Whitelabel brands ship their own version of this file with per-brand
 * CSS-variable overrides. See brands/laboratorio-paseos/brand-theme.css
 * for the reference implementation.
