   Homepage mobile polish — 2026-05-18
   Tightens every section on the index.html homepage for phones.
   Loaded AFTER styles.css so its overrides win on equal specificity.
   Scope is `.hero`, `.partners-strip`, `.about-section`, `.courses-section`,
   `.internship-section`, `.job-section`, `.consultation-section`,
   `.testimonials-section`, `.footer`. The `.platform-section` already has
   its own mobile block inline in index.html.
