AB Clear windows onto emergent hadron mass (EHM) and modulations thereof by Higgs boson interactionsare provided by observable measures of pion and kaon structure, many of which are accessible via generalised partondistributions (GPDs). Beginning with algebraic GPD Ansätze, constrained entirely by hadron-scale and Kvalence-parton distribution functions (DFs), in whose forms both EHM and Higgs boson influences are manifest, numerousillustrations are provided. They include the properties of electromagnetic form factors, impact parameterspace GPDs, gravitational form factors and associated pressure profiles, and the character and consequences of allordersevolution. The analyses predict that mass-squared gravitational form factors are stiffer than electromagneticform factors; reveal that K pressure profiles are tighter than profiles, with both mesons sustaining near-core pressuresat magnitudes similar to that expected at the core of neutron stars; deliver parameter-free predictions for andK valence, glue, and sea GPDs at the resolving scale GeV; and predict that at this scale the fraction of mesonmass-squared carried by glue and sea combined matches that lodged with the valence degrees-of-freedom, with asimilar statement holding for mass-squared radii
