   Skillora design system
   --------------------------------------------------------------------------
   Hand-written re-creation of the Skillora template visual language:
   white pages over a faint wavy-line texture, one teal accent (#05675A),
   flat 1px-border cards (radius 12), restrained shadows, Nunito everywhere,
   playful pre-composed collage imagery. No dark sections.
