/* ============================================================
   product-edit-basics.css  ·  t-004 (worker-4)
   Scope: .pe-section[data-section="basics"] only — Title /
   Description / Category / SKU.

   Rules of engagement (frozen_contract):
   • Reuses the shared .pe-field component owned by t-008
     (product-edit-fields.css). This file does NOT redefine
     field BASE styles (.pe-field__input padding/border/etc.).
     It only handles BASICS-section layout, the category select
     polish, helper-text tidy, and the live char-counter node.
   • Loads AFTER product-edit-fields.css and BEFORE polish, per
     the documented partial order.
   Brand tokens come from colors_and_type.css (--accent = terra-500,
   --canvas cream, --font-display Fraunces, --font-body DM Sans).

   row aligns cleanly regardless and stays single-column on small
