Regression from the pulse-animation commit: the @media (prefers-
reduced-motion) block had crept up and swallowed the .o_fp_step_line
rule, so the connector lines only got flex:1 when the user had
reduce-motion enabled. Everywhere else they had zero width and the
circles clustered on the left of the row with no visible gaps.
Moved .o_fp_step_line back inside the parent .o_fp_stepper { } where
it belongs. Added a comment so the next person doesn't make the same
mistake when editing the surrounding rules.
