/* =====================================================================
   TOOLSGURU — STYLESHEET (polished)
   =====================================================================
   HOW TO EDIT COLORS / BRANDING:
   Just change the values inside :root{ ... } below. Every color used
   anywhere in the site is pulled from these variables, so changing
   one line here updates the whole site.

   NOTE: every class name / id below is unchanged from the original —
   this file only refines values (shadows, spacing, transitions,
   hover states). Nothing in script.js or the HTML needs to change.
   ===================================================================== */
