Bubble Tea TUI Development

Work with the repository's installed Bubble Tea/Lip Gloss versions and existing model/update/view structure. Use current official docs for version-specific API changes; do not assume bundled examples match the consuming project's major version.

Implementation

• Reuse nearby components and state ownership. A small widget does not require a new project scaffold, YAML configuration, hot reload, mouse handling, or effects library.
• Before changing layout, inspect the relevant guidance in references/golden-rules.md. Measure the actual frame/padding and clamp small-terminal dimensions; subtracting a fixed two cells is valid only for that exact border.
• Use terminal-cell/ANSI-aware measurement and truncation. Do not slice strings by byte length or assume code points equal display width. Choose clipping, wrapping, or scrolling for the content's behavior; not all bordered text must truncate.
• Keep hit-testing consistent with the rendered layout and focus state. Proportional sizing is useful for flexible panes; fixed sizes are valid for intentional controls.
• Keep effectful work outside rendering and preserve the model/update lifecycle. Validate the changed interaction and relevant narrow/wide terminal sizes; add an owning test only when behavior lacks coverage.

Bundled templates are optional starting points for a new application. Adapt their API versions and layout assumptions; do not replace a working project structure or add dependencies it does not need. Install required dependencies through the repository's package workflow, not by hand-editing go.mod. Product behavior, terminal constraints, and project conventions take precedence over illustrative examples.
