/* ==========================================================================
   ISIS Fluid Control — Base CSS (Webflow-free foundation)
   Generated 2026-09-16 by Webshape Design. Theme copy for isisfluids-v2 (Manrope self-hosted).

   Purpose: replaces normalize.css + components.css + the Webflow utility
   layer (.w-*) with one self-sufficient foundation. Existing block class
   names (.body-section, .body-container, .title-holder, .button-holder,
   .columns/.column, .main-button) are kept so current templates keep
   working while they are migrated.
