thejayman77 3858380ffe Brief emotional-mix guardrails + source on its own line
Composition (Codex's priority — content mix was the louder problem):
- _select_diverse now guards the daily five's emotional tone: at most 1 health,
  at most 2 science+health combined, at most 2 of any topic, distinct sources —
  so at least three of the five are community/culture/animals/environment when
  available. Caps relax (mix, then source) only to fill on thin days.
- Verified live: today's five went to environment x2, health, animals, science.

UI:
- Source moved to its own line below the tags, left-justified, for uniform
  rhythm across hero and tiles (was sometimes trailing the tags, right-aligned).
- Watermark kept as-is (intentionally subtle; liked).

Tests updated for the emotional-mix contract (80 total).
