/* ===========================================================================
   About page (/about)

   Same surface language as the redesigned profile page:
     1. Hero   – cover, logo, title and mission on one surface
     2. Panel  – one surface holding the Creator, Libraries and Contact
                 sections, separated by hairlines instead of detached
                 card headers

   All colour comes from the shared theme variables, so light / dark / OLED and
   every accent colour work without extra rules.
