A beta tester photographed claude's `❯` prompt and its `⏵⏵` bypass-permissions marker rendering as empty boxes in the preview pane. Their font has no coverage for those codepoints while drawing `·`, `─`, `│` and `▶` perfectly. The glyph TIER cannot help here. It answers "can this terminal do Unicode at all", which is a locale question, and it correctly says yes for exactly the terminals this affects. Coverage is per-glyph and undetectable from inside the process, so the handful of rare glyphs CLIs use as chrome are folded to the ASCII arrows they already look like, and everything a plain font does render is left alone. Scoped tightly: the preview only, never the TUI's own chrome, and skipped entirely at the `nerd` tier where the user has declared a font that can draw anything. The table is short and every entry was seen as tofu in a real terminal rather than guessed at. The fold is length-preserving, so the preview pane's column arithmetic is unaffected.
