docs: Sprint 15 round 3 — +10 recipes, library at 77 total

Sprint 15 round 3 (no new code; reused scripts/seed_recipes.py
from round 1, idempotent) added 10 more Spoonacular recipes to
the local library. 37 duplicates were skipped. Imports: 2
Asian leftovers (pho, kung pao) + 8 American comfort dishes
(chili, meatloaf, mac and cheese, BBQ chicken, pot roast,
shepherd pie, chicken pot pie, beef stew).

DB went 67 -> 77 total recipes (47 Spoonacular + 30 manual).
LLM test (Sprint 13, week 2026-08-03, prompt "comfort food,
no repeats from past 2 weeks"):
  {picked_count: 0, filled_count: 21, failed_count: 0}
21/21 slots filled, 0 failed.

All 6 running docs updated: plan.md (S15R3.1-S15R3.2),
context.md (D11-D13), sprint15-verification.md (round 3
section + 3-round summary table), ui-nielsen-audit.md
(round 3 paragraph), fix-ui-audit.md (T8.7), handoff-ui-
audit.md (TL;DR + Sprint 15 section), HANDOFF.md (round 3
paragraph + Last-updated footer).

Cumulative Sprint 15 work: 46 new Spoonacular recipes across
3 rounds. Library at 77 total — well past the 4-week coverage
threshold.

+- **D11 — Re-ran `scripts/seed_recipes.py` (round 1's script), not a new script.** Round 3 uses the same script as round 1 — it's idempotent, so it skipped 37 duplicates and picked up the cap-blocked queries from round 1 (queries 29-50 were never attempted in round 1).
+- **D12 — Round 3 is the last automatic run.** Library at 77 is well past the 4-week coverage threshold (77 unique vs 84 picks needed = 1.09× rotation). The remaining 12 unrun queries would add 5-10 more (Mediterranean + American leftovers), but the family can hand-curate a round 4 with specific dishes they want rather than running a broad sweep.
+- **D13 — Total Sprint 15 work: 46 new Spoonacular recipes across 3 rounds.** Round 1 = 18, round 2 = 18, round 3 = 10. ~5 minutes of agent time per round. Library trajectory 19 → 37 → 47 (Spoonacular) → 77 total (with 30 manual recipes).
