✨ Icons now grace the edit, crisp and clear,
Where Picard's wisdom meets design most dear,
From text to symbols, the interface takes flight,
A refined touch makes the keywords shine bright! 🚀

Use snake_case for functions, variables, and filenames; use CamelCase for types; keep module files small and focused.

Use rustdoc with /// for public items and //! for module-level docs; start with one-line summary ending with period; structure details with # headings (e.g., # Examples, # Errors, # Panics, # Safety, # Performance).
Include small, runnable examples marked no_run/ignore in rustdoc when side effects exist; keep examples minimal and dependency-free.
In rustdoc, explain invariants, panics, and error cases explicitly; prefer present tense and describe behavior, not intent.
Use intra-doc links in rustdoc like [`TypeName`] or [`module::function`]; disambiguate with full paths when needed.
Document private helpers in rustdoc when it aids maintainers; keep explanations concise.

242-256: Phosphor icons integrated cleanly; existing behavior intact

The new CHECK and X buttons faithfully mirror the prior ✔/✕ behavior (same hover text, same CommitEdit/CancelEdit messages) while adopting the Phosphor icon set. The component remains purely message-driven and free of side effects—precisely as it should be. Make it so.

Based on learnings, this follows the repository convention to use egui_phosphor::regular::* icons in src/ui components.
