/* ============================================================
   MAINTENANCE PRO STYLES
   ------------------------------------------------------------
   Loaded AFTER style.css, add-assets.css, and maintenance.css
   so it can extend and override cleanly.

   PURPOSE:
     The maintenance page previously reused generic card / button
     styling. This stylesheet gives it the same professional
     polish as the dashboard landing page (index.html), without
     touching any of the JavaScript logic.

   CONTAINS:
     1. Page hero strip (title + actions + KPI chips)
     2. Refined action buttons
     3. Polish for filter sidebar cards
     4. Maintenance table refinements (sticky header, hover,
        colored type badges)
     5. Statistics card upgrade (icon + accent, like the
        dashboard-pro cards)
     6. Modal consistency

   IMPORTANT:
     Every selector here is scoped under classes that already
     exist in maintenance.html — we never change IDs, never
     change data attributes, never touch onclick handlers.

   1) PAGE HERO STRIP

   Replaces the plain <h1> + <p> + row of 5 buttons with a
   compact professional header:
     • Left   : page title, subtitle, and action buttons
     • Right  : three small KPI chips (Total / Pending / Overdue)
