📏 A precise ruler scale picker widget for centimeters with a centered indicator, dense major/minor ticks, and a big live numeric readout. Smooth inertial scrolling + snap-to-step makes height/length input fast and accurate — no keyboard needed. ⚡

⚙️ Functionality

• 🎚️ Scrollable ruler track with numbered major ticks + fine minor ticks

• 🎯 Center indicator line — align ticks under the marker to select the value

• 🔢 Large live value with cm unit; configurable precision (e.g., 170.0)

• 📏 Step size & snap (0.1 / 0.5 / 1.0 cm) for consistent increments

• 🚧 Min/Max bounds with clamped selection (e.g., 100–220 cm)

• 🌀 Natural inertial scrolling with gentle deceleration

• 👆 Tap/drag gestures + optional keyboard fine-tuning

• 🔔 Haptics/ripple feedback on step changes (optional)

• 🎨 Theming: accent color (indicator), tick density/length, typography

• 🌍 RTL & i18n: reversible direction + localized number formats

• ♿ Accessibility: high-contrast ticks, large value text, semantic labels

• 🔌 Data-ready: bind to Firestore/Supabase/REST/local state with onChange / onEnd

• 🌗 Light/Dark support with subtle shadows for depth

✅ Great for

🧍‍♂️ height pickers • 👗 garment sizing • 🏃‍♀️ fitness profiles • 🏥 medical/measurement forms • 💰 budgets/limits (with custom units) — any UI needing a precise, touch-friendly numeric input.
