Version 1.0.4

• 50 new concepts — every domain now holds 103 terms, 1,133 in total
• New coverage: transients and multi-messenger astrophysics, stellar
endpoints, distance measurement, exoplanet detection methods, galaxy
scaling relations, observing and analysis techniques
• More precise highlighting — the longest matching term now takes
priority, so "type Ia supernova" is explained as itself
• No changes to permissions, data handling, or privacy
