/*
THESIS: Checkout is one calm guided task, not six disconnected Bootstrap panels.
OWN-WORLD: strict monochrome, warm paper fields, hairline rules, square controls and one black action.
STORY: the buyer always sees where they are, what remains, and how to continue without losing entered data.
FIRST VIEWPORT: a compact title and progress guide frame the active form; the next action remains visually dominant.
FORM: established EDC Store operational surface, extended without changing OpenCart AJAX behavior.
FINISH: unreviewed and undocumented is unfinished; this build ends with the finish review, the verdict, DESIGN.md, and every shipping raster carrying its provenance.
