/* ============================================================================
   Training log — all styling. Editorial composition, portfolio-matched:
   content sits directly on the page background, whitespace and hairline
   rules do the separating, borders are reserved for genuinely interactive
   surfaces (steppers, the active set entry, calendar cells, overlays).

   Theming: dark is the default (defined on :root); html.light overrides the
   tokens. Everything below the tokens is written against roles, never raw
   hex, so the theme swaps in one place.

   Session identity (A/B/C) flows through --stype, stamped by data-stype
   attributes, so a component never hard-codes a session hue.
