   MISSA — header only
   Scoped strictly to the site header (and its hamburger drawer). Colors
   pulled from the MISSA logo: blue #0f70b7, red #e51b20, near-black ink.
   Layout: row 1 = menu | logo+poster | search | connexion
           row 2 = page title, full width
   Several rules re-declare what styleV4.css sets (.titre column layout,
   3em paddings, %-widths) so the legacy look can't leak through.
