/* BBMc switches — language (NL/EN/DE) over target group (5 sectors). Owner: lane A.
   Contract D4. Derived from Jean's skeuomorphic 2-stop toggle, restyled into the
   BBMc tokens and generalised to N stops:

     --n  number of stops      (set inline, server-side)
     --i  active index, 0-based (set inline server-side, updated by segment.js)

   Knob:  left = pad + i * (100% - 2*pad - knob) / (n - 1)
   Track: ink -> ink-deep, inset shadow, gold only as the hairline border.
   Knob:  navy gradient + drop shadow; sky ring = the active indicator, which
          re-animates on change (segment.js toggles .is-changing).
   Markup: see bbmc_switches_html() in build_wp_theme.py (I18N_PHP).
   (2026-09-27: a literal port of the uiverse template was tried and reverted at
   Jean's request — this segmented design is the chosen one.) */
