February 2026 (BibliothecaDAO/eternum) monthly summary: Delivered two major UI enhancements and a session-management upgrade, emphasizing reliability, data accuracy, and user-facing performance. Key features delivered: 1) Night Lighting Optimization: recalibrated night lighting parameters to improve visibility of armies and structures during nighttime gameplay, reducing user friction and enhancing playability. Associated commits improved lighting floors and transition quality (b0203a5f68021a8567cdf79cde9706f196734ccd; cc8fd1ec455a642cd9b16c268887626728a2713f); 2) Troop Count Display Precision: refined the count display to show exact numbers below 10k and one decimal place for 10k and above, with UI consistency across transfer slots (commit cc8fd1ec455a642cd9b16c268887626728a2713f). Authentication and Session Management Improvements: Deferred session creation until a game is selected; recreates keychain iframe with correct contract addresses to avoid sign-manually-then-refresh loops; adds dynamic policy refresh for seamless authentication (commit 0ebfa047dbc67acb5bd40f2049ee8fa12d925dd7). Major bugs fixed: 1) Night lighting floor raised to improve army/structure visibility at night; 2) Under-10k troop counts now display exact figures (and 10k+ shows decimals), eliminating prior rounding. Overall impact and accomplishments: Enhanced user experience during night gameplay, improved data accuracy for troop counts, and more robust, frictionless authentication flows, contributing to higher user satisfaction, reduced transfer errors, and stronger session reliability. Technologies/skills demonstrated: Front-end UI/UX tuning (React/TypeScript), precise numeric formatting, Web3 integration (contract addresses in keychain iframe), dynamic policy refresh, and cross-team collaboration (co-authored commits).
