Adds a single centred line between the feature grid and the "More
views" block calling out that the AI surfaces (strategic log,
indicator reads, portfolio analysis, chat, daily digest) are
available in English and Italian. Cross-cutting feature so it reads
better as a one-line callout than as a 4th feature card without its
own screenshot. Also notes that tickers and numbers stay verbatim
across the toggle, which the prose now guarantees.
