Hero guardrail (core to the promise, not cosmetic):
- New hero.py: the lead story is chosen with a stricter filter than the rest of
the brief — very low cortisol/ragebait and no grief/medical/violence terms
(cancer, glioblastoma, death, diagnosis, ...). Such constructive-but-charged
stories stay among the five; they just never lead by default.
- /api/brief applies user avoid-terms FIRST, then lead_with_gentle, so personal
boundaries always take precedence over the general guardrail.
- Verified live: the brief no longer leads with a glioblastoma story.
Card polish (per review):
- Secondary cards with no real image are now text-first (no row of empty media
bands); hero still always shows media or a typographic fallback.
- Inline tuning actions are quiet until hover/focus on pointer devices, and stay
visible (softer) on touch — less interface machinery.
Tests: hero safety + lead reordering (70 total).
