Examples
in[["margin-left: 48px","padding-right: 12px","text-align: left","border-left: 3px solid var(--accent)","float: right"]]out["margin-inline-start: 48px","padding-inline-end: 12px","text-align: start","border-inline-start: 3px solid var(--accent)","float: inline-end"]

in[["left: 0","right: 12px"]]out["inset-inline-start: 0","inset-inline-end: 12px"]
What a strong answer looks like

Vibe & agentic: describe the solution in plain language (or narrate it) and the coach grades your approach.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
