• There is high merge risk because both findings are high-severity (7–8/10) with high confidence (9/10) and affect active text-editing flows.
• In editor/src/messages/tool/tool_messages/text_tool.rs, lorem ipsum sizing divides by line_height without a zero guard, which can produce extreme word_count values and trigger expensive allocations during drag updates (performance/stability impact).
• In editor/src/messages/tool/tool_messages/text_tool.rs, persistent is_lorem_ipsum state when editing existing layers can carry stale behavior across sessions, suppress clipping warnings, and truncate unrelated text on commit (user-visible data correctness risk).
• Pay close attention to editor/src/messages/tool/tool_messages/text_tool.rs - guard zero line_height math and reset lorem-ipsum state when switching to existing layer edits.

P1: `is_lorem_ipsum` persists across sessions and is not reset when editing existing layers, so stale state can suppress clipping warnings and incorrectly truncate unrelated text on commit.</violation>

P1: Lorem ipsum sizing divides by `line_height` without guarding zero, allowing infinite/huge `word_count` and expensive allocation during drag updates.</violation>

Code Review

This pull request implements a 'Lorem Ipsum' placeholder feature for the text tool, allowing users to automatically fill new text boxes with placeholder text. It includes a new preference setting, UI components, and logic within the text tool's state machine to estimate and truncate the placeholder text based on the drawn box dimensions. The review feedback highlights several improvement opportunities regarding code maintainability and performance, specifically recommending the use of named constants instead of magic numbers for text estimation and suggesting optimizations to reduce string allocations during text generation and truncation.
