 * Photos App theme skin: structural rules that tokens alone can't express —
 * the frosted topbar, the gradient wordmark and primary buttons, pill-shaped
 * nav links and buttons, and the hover zoom on photo tiles. Every rule is
 * scoped to [data-theme="photos-app"], so this file is inert for other
 * themes; palette values come from tokens.css.
 * Mockup reference: design_mockups/03-photos-app.html.
 *
 * Icons reuse the classic theme's line set via mask + currentColor, so this
 * theme ships no icon files of its own — only a favicon and placeholder.
 * Mask longhands only — the `mask:` shorthand resets mask-image, which the
 * lower-specificity per-icon rules below would then lose.
