A prebuilt tool, bin/ludic-ui-preview (built by ludic-dev build, shipped beside ludic-lsp, run as `ludic ui-preview [--font DIR]`): ludic.ui with a backend that records every draw call as a line, and mock component classes the studio describes (load / model / calls). frame t runs ui_show at interface time t; text is measured on the CPU with the game's font.json metrics; locale goes through ludic.i18n; tree / box / rules inspect the frame. No game code, no GPU, no network. The wire protocol is frozen as tools/ui-preview/protocol-v1.md; smoke.txt is a transcript to run. ludic.ui gains, all additive: UiClass.make_of, UiBackend.said / emitted, UiRule.text / at (with comment line breaks kept so rule lines count true, and a class's styles read under its .lss path), and ui_root, ui_find, ui_rules_of, ui_rule_value, ui_building, ui_class, ui_class_load, ui_file_forget, ui_errors_clear; ui_nine_cuts_into exported.
