The paper concludes with lessons learned, a set of reusable components, and a roadmap for extending the Sakura Stand to other cultural themes (e.g., “Maple Autumn” and “Snow‑Flake” stands). 1.1 Motivation Mobile applications that surface real‑time social “heat” (likes, shares, live‑chat bursts, etc.) often suffer from two contradictory user‑experience goals:
This paper documents the complete development life‑cycle of the that drives the Sakura Stand, from requirements analysis through architecture, implementation, testing, and performance evaluation. The script is built in TypeScript + React‑Native , leverages Reanimated 3 , Skia‑Canvas , and GraphQL‑Apollo for data streaming, and follows a Model‑View‑Intent (MVI) pattern to keep UI logic deterministic and testable. Empirical results from a 2‑month field study (N = 1 542 participants) show a 23 % increase in user‑engagement time and a 17 % reduction in perceived latency compared with the baseline Flames Hub UI.

The platform, launched in 2023, provides a flame‑event stream (a lightweight JSON payload describing a user‑generated spark) to millions of mobile users worldwide. Early UI iterations used a minimalist red‑orange gradient, which performed well but lacked cultural resonance in markets such as Japan, South Korea, and Taiwan.
