"""Rebuild the four new pages in META 2027's own visual language.

The first versions were technically compatible — right shell, right stylesheet — but they read
like documents, not like this site: a plain <table> for the dates, inline styles for the scam
warning, undifferentiated card pairs for six symposia. This pass rewrites the bodies using the
components the site already speaks (.tl timeline, .info-card, .alt-band, .btn, .cfp-status) plus
two small additions to meta27.css (.tba-panel, .sym-nav) rather than inline styling.

The shell comes from programme.html at its current state — which now carries the dropdown nav —
so the four pages inherit navigation, footer and scripts without any special-casing. Active state
is then set per page the same way gen_nav.py does it.
