Constant MAX_RANGE_ITEMS 

pub const MAX_RANGE_ITEMS: usize = 10_000;

The most indexes range(n) yields (R8 F51): a Rating’s max of 1e8 or 1e300 would otherwise allocate that many items before the component budget could refuse them. Equals limits::MAX_TEMPLATE_ITEMS; a larger n is silently clamped (the reducer’s maxComponents reports the overflow). Mirrors MAX_RANGE_ITEMS in src/expr.ts.
