## Summary

Community SDK documentation for Mini App theming: representative dark-theme sample values for the core `ThemeParams` keys plus accent, section-header, and destructive samples, and the hard rule to never hardcode colors and always re-read theme parameters on change.

## Key findings

- Dark-theme samples: `bg_color #17212b`, `text_color #f5f5f5`, `hint_color #708499`, `link_color #6ab3f3`, `button_color #5288c1`.
- Further dark samples: `accent_text_color #6ab2f2`, `section_header_text_color #6ab3f3`, `destructive_text_color #ec3942`.
- Apps must never hardcode colors and must never cache them without refresh: re-read theme parameters and color scheme on every `themeChanged` event.

## Pros / strengths

- The only concrete sample values found for the `ThemeParams` keys, and they agree with the Desktop night theme file (`#17212b`, `#f5f5f5`).
- The re-read discipline is stated as a hard rule, not advice, which settles tai's switch contract.

## Cons / limitations / caveats

- Dark samples only: exact default light-theme hexes for the `section_*`, `subtitle`, and `destructive` keys are not published officially (open gap).
- Community docs; samples are representative values from a user-themeable system, not constants to bake in.

## Relevance to tai

Provides the dark defaults for tai's Telegram-derived theme roles and the never-hardcode/re-read-on-switch rule that `set_theme` plus full repaint already implements in spirit.
