New medical_symptoms SQLite catalog with 242 seeded symptom records, 
categories, body systems, tracking notes, urgency-context notes, search 
terms, and MedlinePlus links: [app/bootstrap.php (line 
186)](/Users/tyemeclifford/Documents/GH/workout/app/bootstrap.php:186), 
[seed logic (line 
635)](/Users/tyemeclifford/Documents/GH/workout/app/bootstrap.php:635)
New searchable symptom directory: [public/symptoms.php (line 
1)](/Users/tyemeclifford/Documents/GH/workout/public/symptoms.php:1)
New dynamic per-symptom page, e.g. /symptom.php?id=24: 
[public/symptom.php (line 
1)](/Users/tyemeclifford/Documents/GH/workout/public/symptom.php:1)
Symptom helper/link lookup functions: [app/bootstrap.php (line 
1473)](/Users/tyemeclifford/Documents/GH/workout/app/bootstrap.php:1473)
medicalSymptoms added to the combined library search/API: 
[app/bootstrap.php (line 
2024)](/Users/tyemeclifford/Documents/GH/workout/app/bootstrap.php:2024)
Symptoms added to nav, homepage, and combined medical search: 
[site-header.php (line 
27)](/Users/tyemeclifford/Documents/GH/workout/public/partials/site-header.php:27), 
[index.php (line 
11)](/Users/tyemeclifford/Documents/GH/workout/public/index.php:11), 
[medical.php (line 
13)](/Users/tyemeclifford/Documents/GH/workout/public/medical.php:13)
