Before touching the keyboard, answer these: **What's the emotional core?** - A replay browser is about _nostalgia and rediscovery_—reliving great moments - Match results are about _pride and reflection_—celebrating what happened - Matchmaking is about _anticipation and tension_—building toward something - Leaderboards are about _aspiration and competition_—where do I stand? What is _this_ feature really about? Name the feeling. **What will someone remember?** Pick one element that makes this UI distinctive. Not five. One. Maybe it's: - A satisfying animation when something important happens - A bold use of color that immediately communicates state - A moment of delight that rewards the user's attention - An unexpected bit of polish that shows craft **What's the energy level?** - **High energy**: Match results, rank-ups, achievements, victories. Orchestrated animations, bold colors, dramatic reveals. - **Medium energy**: Browsing, discovery, social features. Smooth transitions, clear hierarchy, moments of personality. - **Low energy**: Settings, configuration, system UI. Clean, efficient, invisible. The UI gets out of the way. Match the energy to the moment. Not everything needs to be exciting—but the exciting things need to _feel_ exciting. ## What Bold Looks Like Here A few moments in ShieldBattery that show the level of craft to aim for: **The post-match rank reveal.** When your division changes, the icon doesn't just appear—it scales in with a spring bounce, brightness flares, and a sound plays. That half-second of choreographed animation transforms "you ranked up" from information into _feeling_. **Win/loss colors you can read across the room.** Match results don't use subtle tints. Victories are bright green (`--theme-positive`), defeats are clear red (`--theme-negative`). There's no ambiguity. The color _is_ the message. **The draft screen timer.** As time runs low, the color shifts from calm to amber to urgent red. You feel the pressure without reading a number. The UI communicates through instinct, not interpretation. **Staggered point reveals.** In the post-match dialog, your points and rating don't appear all at once. They animate in sequence—points first, then rating—with sound cues on each reveal. The delay creates anticipation; the stagger creates rhythm. These aren't decorations. Each one makes the experience _feel_ like something. That's the bar. ## The ShieldBattery Identity This is a platform for competitive StarCraft players. The UI should feel like it respects their time and skill: **Precise, not sloppy.** Alignments matter. Spacing is intentional. Nothing feels accidental. **Responsive, not sluggish.** Interactions acknowledge input immediately. Animations have purpose, not padding. **Confident, not timid.** When something is important, make it important. Don't hedge with muted colors and small text when the moment calls for boldness. **Crafted, not generic.** A ShieldBattery feature should feel like it belongs to ShieldBattery, not like it was pulled from a template. **Cohesive, not cobbled.** Every visual element—icons, colors, typography—comes from the design system. No emoji, no mismatched icon sets, no borrowed aesthetics. ## Making Bold Decisions You have permission to: **Use the full color palette.** The design system has semantic colors for a reason—`--theme-positive` for wins, `--theme-negative` for losses, race colors for faction identity. When the context calls for it, _use them confidently_. **Create moments with motion.** The project uses `motion/react` for orchestrated animations. A well-timed staggered reveal or a satisfying spring animation can transform a feature from functional to memorable. See `post-match-dialog.tsx` for how this is done well. **Establish visual hierarchy ruthlessly.** Not everything is equally important. Make the important things big, bold, and obvious. Let secondary information recede. If you're not sure what's most important, that's a design problem to solve before coding. **Let the content breathe.** Generous spacing isn't wasted space—it's emphasis. Dense UIs have their place, but know when you're building a cockpit vs. a gallery. ## What to Avoid **Emoji as UI elements.** Never use emoji (🎮 ✅ ⚠️ etc.) for icons, status indicators, or decorative elements. They clash with the crafted, professional aesthetic. Reach for `MaterialIcon` instead—there's a symbol for virtually every concept. **Generic placeholder aesthetics.** Don't fall back on common patterns just because they're easy. A checkbox list with emoji bullets isn't ShieldBattery—it's a to-do app. ## Asking the Right Questions When you're stuck, these questions usually help: - What would make a player _want_ to show this to a friend? - If I removed this element, would anyone miss it? - What's the most important thing on this screen? Is that obvious in 2 seconds? - Am I being bold because it serves the user, or just because I can? - Does this feel like ShieldBattery, or could it be any app? ## Technical Grounding The design system provides the vocabulary. Use it: - **Colors**: `client/styles/colors.ts` — theme variables, race colors, container elevation - **Typography**: `client/styles/typography.ts` — Inter for body, Sofia Sans for titles, defined scale - **Components**: `client/material/` — buttons, dialogs, inputs, menus (extend, don't recreate) - **Animation**: `motion/react` with spring physics, `client/material/curves.ts` for CSS transitions - **Icons**: `MaterialIcon` component with [Material Symbols](https://fonts.google.com/icons) - **Never use emoji** in the UI. Use MaterialIcon for visual indicators. Emoji break visual consistency and feel out of place in a competitive gaming platform. For patterns, look at existing features: - `post-match-dialog.tsx` — orchestrated animations, staggered reveals, sound integration - `mini-match-history.tsx` — interactive lists, semantic colors for results - `draft-screen.tsx` — timer states, urgency through color **Use `$`-prefixed props** for styled-components (`$active`, `$disabled`, `$focused`). --- **The goal is not to be safe. The goal is to be intentional.** A boring UI is a failure of imagination. A chaotic UI is a failure of discipline. The best ShieldBattery features are bold _and_ cohesive—they have personality that serves the player. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/shieldbattery) — claim your Tome and manage your conversions.
