LEARN IS NOW A REAL COURSE. The Learn section used to deal out the same one-line definitions as flashcards. It has been rebuilt as twenty-three written chapters — one per unit, twenty-five to seventy minutes of reading each. - Chapters now name the material instead of summarizing it: every antimicrobial class with its target, spectrum and resistance mechanisms; the stains step by step; every pathogen by body system with transmission, distinguishing sign, diagnosis and treatment; the meningitis CSF table; the hepatitis A-E comparison; food intoxication versus infection onset windows. - Each chapter reads as continuous text with section headings, key-fact boxes, worked examples and clinical correlations, opens with that unit's real lab slide, and ends with a button into its quiz. - All of it is original material, fact-checked in four independent passes against Tortora, Madigan and Murray. STUDY CARDS NOW TEST RECALL The shuffled deck no longer duplicates Learn. The answer is blurred behind a tap-to-reveal veil, so you commit to an answer before you see it. Read the chapter, then drill the cards. ALSO IN THIS RELEASE - The About screen now carries a full Content & Image Attribution section naming the licenses behind every Slide Lab image - Corrected the in-app version string and the description of how Learn works - Accessibility and layout polish throughout the reading view
