/* =====================================================================
   ViccoFitness — App shell + component library
   ---------------------------------------------------------------------
   Consumes tokens.css. Styles the authenticated product (dashboard,
   clients, exercise picker, session forms, templates, reports, login)
   to one cohesive, distinctive system. Mobile-first; bilingual-safe
   (no fixed widths that break on longer EN strings, compact for 中文).
   All behaviour, htmx/Alpine hooks and i18n strings are untouched — this
   is presentation only.
