/* ===========================================================================
   Anchor India Automations — shared UI stylesheet
   ---------------------------------------------------------------------------
   NOTE ON !important
   The markup in this project sets colours and borders as INLINE styles
   (style="color:var(--text)"). An inline style always beats a stylesheet rule
   no matter how specific the selector, so a plain `:hover{color:...}` rule
   silently does nothing. The `!important` flags below are what actually let
   these hover states win. Do not remove them unless the matching inline
   colour/border is removed from the HTML at the same time.
