// ========= EXPLANTION FOR 0.2% @ step timing [min. 0.2%] ===========
/*
### Time Approach
// all below values can make the time interval > 250ms
// 250ms (practical value) refers to the minimum frequency for timeupdate in most browsers (typically, shorter timeupdate interval in modern browsers)
if (totalDuration > 400000) stepInterval = 0.2; // 400000ms with 0.2% increment => 800ms
else if (totalDuration > 200000) stepInterval = 0.5; // 200000ms with 0.5% increment => 1000ms
else if (totalDuration > 100000) stepInterval = 1; // 100000ms with 1% increment => 1000ms
else if (totalDuration > 50000) stepInterval = 2; // 50000ms with 2% increment => 1000ms
else if (totalDuration > 25000) stepInterval = 5; // 25000ms with 5% increment => 1250ms
### Pixel Check
// Target Max Pixel Increment < 5px for Short Period Ticker (Rapid Background Change)
// Assume total width <= 99px for short period ticker, like small donation & member welcome
99px * 5% = 4.95px < 5px [Condition Fulfilled]
### Example - totalDuration = 280000
totalDuration 280000
stepInterval 0.5
numOfSteps = Math.round(100 / stepInterval) = 200
time interval = 280000 / 200 = 1400ms <acceptable>
### Example - totalDuration = 18000
totalDuration 18000
stepInterval 5
numOfSteps = Math.round(100 / stepInterval) = 20
time interval = 18000 / 20 = 900ms <acceptable>
### Example - totalDuration = 5000
totalDuration 5000
stepInterval 5
numOfSteps = Math.round(100 / stepInterval) = 20
time interval = 5000 / 20 = 250ms <threshold value>
### Example - totalDuration = 3600
totalDuration 3600
stepInterval 5
numOfSteps = Math.round(100 / stepInterval) = 20
time interval = 3600 / 20 = 180ms <reasonable for 3600ms ticker>
