 * What:  Foundation styles loaded on every page UNCONDITIONALLY.
 *        Includes: CSS reset, self-hosted Poppins @font-face, CSS variables
 *        (the design tokens — colours, spacing, radius, shadow), base
 *        typography, button + form primitives, then @imports of every
 *        per-component stylesheet under components/.
 * Why:   Single, predictable cascade. Component sheets here, layout in
 *        desktop.css + mobile.css. Keeps the cascade reviewable.
 * Used:  Linked from views/_layout.ejs (always).
