/* =========================================================================
   NMF Waste Management — Shared Design System
   One stylesheet, linked by every template, so the whole app reads as one
   consistent product. Component class names match what each page's inline
   <script> already hooks into (sidebar, modal, flash, filter-select, etc.)
   so no HTML/JS had to change — this file only changes how things look.
