Move agent detection into the client list, simplify usage filters and pagination, and route interface text through the shared type scale. Subpage navigation now uses underlined tabs instead of segmented controls.
Darken secondary text on white surfaces, keep long labels readable, and move the OAuth browser picker and quota actions onto existing rows instead of separate lines.
Use the home page background across pages, remove redundant titles, and match the usage records tabs and filters to the shared controls. Move the API refresh and add actions beside search, and drop the standalone provider total.
Adopt a white theme, add home-page shortcuts, and show usage metrics with color-coded details, automatic units, and explicit estimated-cost coverage. Update the README screenshots.
