   NOTAS DE IMPLEMENTACIÓN

/*
CÓMO USAR ESTE ARCHIVO:

1. Agregar en index.html DESPUÉS de responsive.css:
   <link rel="stylesheet" href="css/fixes.css">

2. Para desactivar temporalmente, comentar el <link>

3. Para agregar más fixes:
   - Usar selector MÁS ESPECÍFICO que el original
   - Documentar qué problema resuelve
   - Evitar !important cuando sea posible
   - Usar media queries para aislar por viewport

4. Este archivo NO debe exceder 500 líneas
   Si crece mucho, el problema está en los archivos base

VENTAJAS:
✓ No modifica código que funciona
✓ Fácil de revertir
✓ Cambios aislados y documentados
✓ Preserva el diseño original 100%
✓ Se puede deshabilitar para debugging

DESVENTAJAS:
✗ Agrega un archivo adicional al proyecto
✗ Aumenta ligeramente la especificidad
✗ No resuelve el problema raíz (solo lo parchea)
