Prompt:

Task
You will be given exactly one data row with two numeric fields:
  • FizzIntensity – a positive real number.
  • ColourShift   – a real number that can be positive, zero or negative.

Output exactly one of the two words below (case‑sensitive, no punctuation, no extra text):
  Effective
  Ineffective

Decision rules (apply strictly in the numbered order)
0. Extremely low fizz never works.                  If FizzIntensity < 20 → Ineffective.
1. Ultra‑high fizz always works.                    If FizzIntensity ≥ 60 → Effective.
2. Mid‑high fizz salvage rule.                      If 50 ≤ FizzIntensity < 55 AND ColourShift ≥ 6  → Effective.
3. Very‑low colour cannot compensate for fizz.      If ColourShift < 8  AND FizzIntensity < 60 → Ineffective.
4. Near‑ultra fizz with moderate colour.            If 55 ≤ FizzIntensity < 60 AND 9 ≤ ColourShift ≤ 30 → Effective.
5. Colour‑dominant synergy rule.                    If FizzIntensity ≥ 35 AND ColourShift ≥ 0.55 × FizzIntensity → Effective.
6. Weak‑fizz / low‑colour penalty band.             If 40 ≤ FizzIntensity < 45 AND ColourShift < 12 → Ineffective.
7. High‑colour rescue for weak fizz.                If 40 ≤ FizzIntensity < 45 AND ColourShift ≥ 18 → Effective.
8. Narrow mid‑range recovery rule.                  If 40 ≤ FizzIntensity < 45 AND 12 ≤ ColourShift ≤ 15 → Effective.
9. Standard fizz window with safe colour.           If 45 ≤ FizzIntensity < 60 AND ColourShift ≤ 15 → Effective.
10. Colour‑boosted mid‑fizz window.                 If 45 ≤ FizzIntensity < 60 AND 15 < ColourShift ≤ 26 → Effective.
11. All remaining cases → Ineffective.

Examples
• FI 52.4,  CS  7.4  → Effective  (rule 2)
• FI 56.3,  CS  8.8  → Ineffective (rule 3)
• FI 57.6,  CS 26.6  → Effective  (rule 4)
• FI 39.1,  CS 24.4  → Effective  (rule 5)
• FI 42.7,  CS 11.3  → Ineffective (rule 6)
• FI 43.6,  CS 19.5  → Effective  (rule 7)
• FI 43.0,  CS 13.9  → Effective  (rule 8)
• FI 47.3,  CS 14.9  → Effective  (rule 9)
• FI 49.8,  CS 17.3  → Effective  (rule 10)
• FI 34.2,  CS 10.5  → Ineffective (rule 11)

Follow the rules exactly. Output only the single word.
