/* ============================================================================
   THE PAPERLESS PIANO TEACHER — site.css
   The ONE shared stylesheet. Every page links this file and never redefines
   anything in it. Page-specific styles go in a small <style> block on that
   page, and must not touch any class defined here.

   ⚠️ THE PADDING TRAP — read this before adding any layout class.
   Classes that sit on the SAME element as .wrap (e.g. <section class="wrap hero">)
   must NEVER use the `padding` shorthand. It silently overwrites .wrap's
   horizontal padding and the text ends up flush against the phone screen.
   Use padding-block (vertical only). This bug is invisible on desktop.
