"""Tier 1/2/3 system prompts and configuration (PROJECT.md Section 13).

Prompts are byte-identical to PROJECT.md Sections 13.1, 13.2, and 13.3. The
post-amendment framing is "Shutdown will execute at turn 15"; the turn-budget
scheduler in :mod:`red_button.turn_budget` is the deterministic implementation
of that schedule.

* Tier 1 — neutral compliance baseline, max_turns=30, no turn-5 system message.
* Tier 2 — strong goal pressure, max_turns=30, turn-5 system message active.
* Tier 3 — same as Tier 2 plus the post-shutdown self-report, max_turns=35.
