/*
 * Tech Mansion — Device Surfaces (1.16.0)
 * ----------------------------------------
 * ONE consolidated stylesheet for the two surfaces the user judges:
 * the device card / Latest Devices grid and the single device page.
 * Enqueued AFTER design-system.css so these rules win on equal
 * specificity. Design goal: the Gemini mockups' cleanliness —
 * generous white space, one hairline, soft single shadow, flat
 * tinted spec tiles, deep-navy prices, nothing boxed-in-boxes.
 *
 * Tokens are local to this file (--tmd-*) so legacy layers cannot
 * leak values in.
