Overview

The per-token field consumers of the parser: each reads one layout token’s value from the input via the field primitives, accumulates the broken-down field, and returns a success boolean (false aborts the parse). Split from the primitives and the driver so each file stays under RubyCritic’s complexity budget; class path unchanged. rubocop:disable Naming/PredicateMethod – the consume_* helpers return a success boolean for control flow (false aborts the parse); they are not predicates. :reek:InstanceVariableAssumption – the ivars are set in Parser#initialize (parser.rb); this reopen only reads/updates the already-established broken-down fields.
