Use tray/overlay for secondary actions (settings, copy link). Progressive disclosure; avoid crowding the main screen. - **Fluidity**: Smooth, purposeful transitions (view changes, modals). Reuse or morph elements for continuity. Avoid static jumps and redundant or decorative animation. - **Delight**: Polish and small surprises in high-impact moments (landing CTA, move confirmation, game end). Avoid sprinkling motion everywhere; follow a delight–impact curve. ## Typography and brand - **Instrument Serif** for brand and headings (e.g. main "FediChess" title, section headings). - Body text: neutral sans for readability. - Reference `.agents/skills/frontend-design/SKILL.md` for typography, color, and motion details. FediChess design principles are the project design language. ## When to use Use this skill when the user asks to change or add UI, layout, animations, or styling in FediChess (landing, lobby, game, or shared components). --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/hktitan) — claim your Tome and manage your conversions.
