The user pointed out that the only genuinely per-user AI surface is
portfolio analysis. The strategic log AND the email digest are both
shared cycles — generated once per cycle, consumed by many users.
For the digest, this means:
- _generate_variants still produces one English variant per tone (as
today, unchanged)
- A new helper translates each variant once per active non-en lang in
parallel via asyncio.gather, producing a {(tone, lang): content}
table for the duration of the job run
- The per-user send loop selects (user.digest_tone, user.lang),
falling back to the English variant of the same tone on miss
Translation count per run = tones × non-en active langs = 3 today.
100 Italian users no longer mean 100 translation calls.
