Language switcher was two inline emoji-flag buttons -- emoji flag
rendering is inconsistent across OS/browsers (some render as two-letter
country codes instead of a flag). Replaced with hand-rolled inline SVG
flags (no new dependency for two locales) inside a proper dropdown
menu, trigger showing the current language's flag.
Also added a 9th Home highlight (personalized recommendations, same
copy already written for the Features page) so the lg:grid-cols-3
feature grid's last row has 3 items instead of 2.
