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 THIS ORDER – stop at the first rule that matches)
0. Ultra‑high fizz always works.                         If FizzIntensity ≥ 60 → Effective.
1. Extremely low fizz never works.                       If FizzIntensity < 20 → Ineffective.
2. Colour‑oversaturation at low fizz fails.              If ColourShift > 25  AND FizzIntensity < 50 → Ineffective.
3a. Low‑fizz colour‑dominant synergy.                    If FizzIntensity < 35                        AND ColourShift ≥ 0.55 × FizzIntensity → Effective.
3b. Mid‑fizz strengthened colour synergy.                If 35 ≤ FizzIntensity < 45                  AND ColourShift ≥ 0.60 × FizzIntensity → Effective.
4. Mid‑high fizz, low‑colour salvage window.             If 50 ≤ FizzIntensity < 55  AND  6 ≤ ColourShift ≤ 12  → Effective.
5. Near‑ultra fizz with some colour.                     If 55 ≤ FizzIntensity < 60  AND  8 ≤ ColourShift ≤ 30  → Effective.
6. Very‑low colour cannot compensate.                    If ColourShift < 8   AND FizzIntensity < 60 → Ineffective.
7. Weak‑fizz / low‑colour penalty band.                  If 40 ≤ FizzIntensity < 45  AND ColourShift < 11 → Ineffective.
8. High‑colour rescue for weak fizz.                     If 40 ≤ FizzIntensity < 45  AND 18 ≤ ColourShift ≤ 21 AND ColourShift ≥ 0.46 × FizzIntensity → Effective.
9. Narrow mid‑range recovery rule.                       If 40 ≤ FizzIntensity < 45  AND 11 ≤ ColourShift ≤ 16 → Effective.
10. Standard mid‑fizz with safe colour.                  If 45 ≤ FizzIntensity < 60  AND ColourShift ≤ 14 → Effective.
11. Colour‑boosted mid‑fizz window (ratio guarded).      If 45 ≤ FizzIntensity < 60  AND 14 < ColourShift ≤ 22  AND ColourShift ≥ 0.32 × FizzIntensity → Effective.
12. Oversaturated mid‑fizz fails.                        If 45 ≤ FizzIntensity < 60  AND ColourShift > 22 → Ineffective.
13. All remaining cases → Ineffective.

Examples
• FI 52.4,  CS  7.4   → Effective  (rule 4)
• FI 58.3,  CS 18.1   → Ineffective (rule 11 fails ratio; rule 12 not hit; default 13)
• FI 57.8,  CS 23.2   → Effective  (rule 5)
• FI 36.8,  CS 25.9   → Ineffective (rule 2)
• FI 29.7,  CS 18.2   → Effective  (rule 3a)
• FI 42.9,  CS 10.7   → Ineffective (rule 7)
• FI 43.1,  CS 14.2   → Effective  (rule 9)
• FI 47.5,  CS 13.6   → Effective  (rule 10)
• FI 49.9,  CS 17.4   → Effective  (rule 11)
• FI 34.2,  CS 10.5   → Ineffective (rule 13)

Follow the rules exactly. Output only the single word.
