Add the Academy: narrated, animated roasting & brewing lessons; cupping link on roast detail
Test and deploy / test-and-deploy (push) Successful in 53s
Test and deploy / test-and-deploy (push) Successful in 53s
Academy (/academy, 'Learn' nav group): - 10 lessons / 45 slides across two tracks. Roasting: seed anatomy and composition, drying & the turning point, Maillard, first crack & development (DTR), curve/RoR reading (crash, flick, stall), defects → one-change discipline. Brewing: extraction physics (dissolving order, yield, grind, temp/time/ratio), then technique per brewer family — immersion (French press, AeroPress, Clever/Hario Switch, cold brew, cupping), percolation (bloom, V60, Chemex/Kalita, batch, percolator), espresso & pressure (puck prep, shot reading, dialing in, moka) - One cohesive scene system: 25 parameterized animated SVG scenes drawn from the app's palette (beans, curves, phase bars, brewers reusing the silhouette library), CSS keyframe animations, reduced-motion support - Narration: Azure TTS (en-US-Andrew HD, eastus) pre-generated to 45 committed MP3s by scripts/generate-academy-audio.mjs; slides speak phonetic respellings (my-YARD, KEM-ex, MOH-kah…) while captions show normal spelling; hands-free autoplay advances after each clip - Player: slide dots, keyboard arrows/space, per-slide captions Roast detail: 'Open cupping session' button next to cup notes (opens or creates the linked plan's session) — its score and flavors flow into the updated .alog download.
