/* ====================================================================
 * MindAttic.UiUx -- Themes/Hardware/theme.css
 * Clean light/dark documentation aesthetic for hardware / maker landing
 * pages. Used by Claudia, ChiMesh, and any future hardware-themed
 * landing page declaring theme: "Hardware" in MindAttic.Deploy.
 *
 * Composes with OutfitFont + AtticFont + BackHomeM. Does NOT load the
 * Cyberspace effects engine -- this is the calm, non-animated counterpart
 * to Themes/Cyberspace.
 *
 * Color scheme follows prefers-color-scheme; no JS toggle in landing pages.
