/* Sharpenly After Screens — mockup CSS, ported verbatim from
   c:/tmp/sharpenly_after_screens.html (rendered by Claude Design).

   Everything below is scoped under `.aft` so it only applies to screen
   containers that opt in by adding the .aft class. This lets the mockup's
   exact pixel placement, shadows, fonts, and spacing override the app's
   pre-existing CSS *only on the screens that have been ported*. Other app
   screens (admin, lessons, badges, etc.) keep their existing styling.

   Path 1 (wholesale CSS adoption) per the design-lock plan. */

   here only for the values the mockup needs that may differ) --- */

/* .aft padding wins over any other .screen rule (including
   body.has-bottom-nav .screen) by using !important. */
/* Only ACTIVE .aft screens render. The base .screen{display:none} would
   normally hide siblings, but our display:flex was overriding it for all
   .aft screens — causing the inactive screens' topbars to bleed through. */
