/* ==========================================================================
   SofterTap site CSS v2 (2026-10-20) — GeneratePress child theme + Rank Math
   System fonts only (nothing loaded from Google). One white page, 760px
   reading column + 300px sidebar on desktop, single column on mobile.
   Signature: the 4-step USGS hardness ribbon (soft → very hard).
   Ad slots (.st-ad) reserve their height so ads never shift the text (CLS).
