/* ==========================================================================
   Lock Screen
   --------------------------------------------------------------------------
   Styled to match https://aakash-sharma.vercel.app's lock screen (measured
   directly from its rendered DOM): the SHARP, unblurred wallpaper — no
   backdrop-filter or glass card anywhere — solid-white "SF Pro Rounded"
   time at 110px/800 weight with a plain drop-shadow, the date in the same
   rounded family directly below it, and a light, quiet unlock hint near the
   bottom. Weather/battery (requested separately, not present on that
   reference) are folded into a small plain-icon row so they don't
   reintroduce the card/blur look this reference deliberately doesn't use.
