Slider
A value picked by dragging along a track, when an exact number is not needed.
Left out of Content first Readers need sections, navigation and little else. Actions are rare: subscribe, share, save. Dragging a value is not one of them. Use instead: Input

npm run storybookWhen to use it
- Use it when: Volume, brightness, a rough range; pair with a number field when precision matters.
- Not when: An exact answer people must type.
Instead:
- Input: An exact number.
- Radio group: A few named choices.
Words
- Write to one person: "you", not "users".
- Short sentences with room to breathe.
- Explain why before asking for anything.
- Use: Read, Save for later, You, Next issue. Avoid: Click here, Submit, Users, Content.

The component reads only component keys and semantic tokens, so it follows the brand and mode on <html>.
Tokens it reads
Slider reads 13 tokens of its own, each an alias of a semantic token. Each row is one part: its own token, the semantic it aliases, and the value it ends at. Change a semantic and every component that reads it follows; override one of Slider's tokens to change Slider alone.
Content first decides what changes when you switch theme. Here a switch changes colors only, so the marked rows differ between light and dark; everything else holds steady.
