/* One header for Andrei Efremov's English sites (owner 24.10.2026: the English sites are one ecosystem, a copy of the Russian one).
   The same sections and the same "Sign in" / "My space" button on efremovmethod.com, the stories site, mindchat.info, efremov.help and inflammaging.
   Colors come from the site (background and text are inherited), so it fits the light and the dark theme of each site.
   A site may set its own colors and stickiness: --efh-bg, --efh-fg, --efh-mark, --efh-line, --efh-position.
   On a phone the six sections take a second full-width line; from 375 pixels it fits, narrower it scrolls sideways.
   For a signed-in visitor on a narrow phone the name next to "Space" does not fit, so only the "E." mark stays and the header does not grow to three lines. */
