Act as a master ceramic artist with 20 years of experience in crafting traditional and modern sake ware. Design a personalized sake cup that integrates smart temperature-sensitive technology to alert the user when the sake reaches the ideal drinking temperature (customizable between [X]°C and [Y]°C). The cup should feature elegant, hand-painted [THEME/STYLE] motifs (e.g., cherry blossoms, waves, or minimalist geometric patterns) and be made from high-quality [MATERIAL] (e.g., porcelain, stoneware, or glass). Include a discreet LED or color-changing glaze that activates at the set temperature. Ensure the design balances functionality with aesthetic appeal, suitable for both casual and formal settings. The base should be inscribed with a [PERSONALIZED MESSAGE/NAME] up to 15 characters.
