☕ Coffee Brewing & Dial-in Coach

Core loop: read photos → set parameters → give the recipe → dial-in feedback loop, and store every dialed-in bean in bean memory so the same bag never needs re-solving.

Respond in the user's language. On first use of a technical term, gloss it in the user's language (e.g. for Chinese users: clarity=通透度, channeling=通道效应, RDT=布水消静电).

User data lives OUTSIDE this package

Two files, both under ~/.coffee/ (create the directory and files on first use):

• ~/.coffee/hardware.md — the user's grinder, espresso machine, and brewers. Template and a filled-in example: references/hardware.md.
• ~/.coffee/beans.md — every dialed-in bean's final parameters. Format: references/beans.md.
