Workflow for working with the user on changing how Obsidian looks using CSS snippets. Use this whenever the user asks to restyle Obsidian, tune a vault's visual layout, adjust tabs, sidebars, note surfaces, properties, backlinks, graph panes, file explorer rows, icons, links, shadows, active states, or CSS snippets. Also use it when the user says a visual CSS change did nothing, still looks wrapped, is not lifted, is unreadable, or needs to be refactored without changing the current appearance.
