 | ❌ removed `opacity` tokens        | we use only 1 opacity (0.4) for all components                                                                                                                                                                                                            | If you use some of the tokens like `--db-opacity-sm` you might run into issues with your layout                                                                                                               |

 | 🔄 moved `_font-sizes.scss`        | We moved the file to another folder to align the same structure as icons or colors.

 | 🔄 ❗ refactored `colors`          | All colors changed. We use color-palettes to generate speaking-names (check `@db-ui/foundations/scss/colors/_variables.scss` to see a list of available tokens). We removed `base` color, it was the same like `neutral`. Add different background level. | 1. Replace all `base` colors with `neutral`<br/>2. If you use the color class replace `db-bg-x` with `db-x-bg-lvl-1`<br/>3. Replace `border-strong`/ `border-weak` tokens with `contrast-high`/`contrast-low` |
