   buttons.css — BarangayConnect
   All interactive clickable elements.
   Import AFTER main.css. CSS custom properties
   live in main.css — do NOT redeclare :root here.

   WHAT IS IN HERE:
     · Base button (.btn) with shared states
     · Size modifiers (sm, lg, full, rounded)
     · Solid variants (green, orange, red)
     · Outline variants (outline, outline-hero, white, dashed, ghost)
     · Filter pills and category/tab pills
     · Icon-only buttons (edit, delete, close, call)
     · Toggle switch component
     · FAB (floating action button)
     · Selector cards
     · Dashboard action buttons
     · Loading spinner state
     · Widget (glass tile) buttons

   WHAT IS NOT IN HERE:
     · Non-interactive labels/pills   → components.css
     · Modal / drawer layout          → frames.css
     · Form inputs                    → main.css

   REQUIRED IMPORTS:
     <link rel="stylesheet" href="css/shared/main.css" />
     <link rel="stylesheet" href="css/shared/buttons.css" />
