// === Arduino-compatible Utility Functions ===

ceil(value)                 // Round up to nearest integer

// === Lambda Helper Functions (NEW - from BaseChannelSequence.cpp) ===

// 1. Simple sequential pattern:

// 2. Arduino-style random pattern:

    set(pin_ptr_[channel], true);

// 3. Wave pattern using helper functions:

// 4. Random LED activation:
for (let i = 0; i < 15; i++) {

// 5. Fill from center (bidirectional):
for (let i = 0; i < halfSize; i++) {

    set(pin_ptr_[halfSize - 1 - i], true);
