   Replaces the old full-screen celebration modal/overlay. A level-up is now

   takeover, never anything post-sized. This is intentionally separate from
   the ALWAYS-VISIBLE inline badge next to a username (sf_render_badge_for_user(),
   .i_inline_lvl_badge below), which never animates and is the permanent
   record of a user's tier; this toast is only the one-off "you just leveled
   up" confirmation and disappears on its own. Same 10-tier icon/tint set as
   the rest of the badge system — only WHERE/HOW LARGE it renders changed. */
