/* ============================== Icons ==============================

   No external CDN dependency for icons — everything renders offline.

   Icon-weight RULE:

              Inherits the parent's text color.
       fas  = toggled-on / active state ONLY
              (filter when filtered, bell when on, etc.)
              Renders in PRIMARY BLUE (#1F68A8) by default — the standard
              "this is engaged" cue used across toolbars, dropdowns, and
              icon buttons. Don't override with semantic colors (yellow on
              star, red on heart, etc.) — the blue treatment handles all
              toggle states.
