You are using Twemoji on kirupa.com. Reuse the pinned catalog and browser in tools/twemoji_browser.htm; do not fork its search data or substitute a different emoji version. Keep search, multi-category filters, Copy SVG, and SVG/PNG downloads working. Twemoji artwork is invariant: theme only its surrounding UI. Preserve CC-BY 4.0 graphics attribution and MIT code notices. Give meaningful images purposeful alt text and hide decorative duplicates. Surface network and clipboard failures rather than showing false success. Keep embedded theme state local and do not write site preferences.

Follow WCAG 2.2 AA for new or changed content: semantic HTML, keyboard access, visible focus, readable contrast in every theme, text alternatives, labeled controls, and explicit errors. Support zoom/reflow, respect reduced motion, and keep sound optional. Read /design/sections/accessibility.md for acceptance checks. Report unresolved barriers; automated checks alone do not establish conformance.
