/* =====================================================================
   Trainingstracker – Stylesheet
   ---------------------------------------------------------------------
   Design-Idee: helles, frisches, motivierendes "In-Bewegung"-Gefühl.
   - Grundfarbe: warmes, leicht grünliches Off-White (kein reines Weiß)
   - Aktionsfarbe: frisches Minz-Türkis (Fortschritt, Bestätigung)
   - Intensitätsfarbe: energiegeladenes Korallrot (PRs, laufender Timer)
   - Tinte statt Schwarz für Text (wärmer, weniger hart)
   Layout bewusst großzügig & großschriftig, damit alles auch vom Sofa
   aus auf dem Fernseher lesbar ist.
