Ep47 post-mortem: fixed theme ignored by callers (backgrounds now
regenerate when theme is set), style-to-model race condition (fallback
to sonnet instead of pool[0]), removed bad pronunciation fixes, added
age-awareness to voice matching, raised MIN_RESPONSE_WORDS to 50.
Swapped problematic model mappings: conspiracy→qwen, know_it_all→mistral,
quiet_nervous→llama, emotional→kimi.
Added GET /api/show/preflight endpoint with 4 checks: model diversity,
theme penetration, voice-age alignment, response coherence (2-exchange
simulation of all callers). Frontend preflight modal with expandable
check cards.
Fixed active caller button not highlighting (moved highlight code before
potentially-failing caller info panel code).

The 2+ requirement created a catch-22: regulars couldn't return because they
needed 2 calls, but couldn't get a second call without returning. Dynamic
count already prevents flooding.

Only inject 2 returners if pool has 3+ eligible (so it's not the same every show).
With 2 eligible, inject 1. With 1 or 0, inject none.

Callers now have strong food opinions (Sparky's green chile, Blake's
Lotaburger, etc.), nostalgic memories of how their town used to be,
and 60% chance of having a strong reaction to a previous caller that
they bring up early in the call by name.
