Static vs Dynamic Allocation

In this lesson:

• the allocation spectrum: static → pool → arena → general malloc
• why general malloc is risky on constrained systems (recap + DSA angle)
• the pool allocator: O(1), fragmentation-free, fixed-size blocks
• the arena/bump allocator: trivially fast, free-all-at-once
• choosing the right strategy for your data structures

The C module covered the heap's hazards; here we choose how to give containers memory when the heap is off the table.
