Release 1.5.1

Touch and keyboard feedback in the shared chrome (owner feedback: phones flashed a theme-blind blue box over anything tapped). The navbar, its dropdowns, the launcher, the drawer and the footer turn off -webkit-tap-highlight-color, show a slight press (scale, which composes with existing transforms) and give keyboard focus one ring in the theme accent. Rules are wrapped in :where() so they carry zero specificity: the chrome's own :focus-visible rules and host pages still win. With reduced motion the press is a brief dim instead of a shrink.
