	calendar_store.c
	The active calendar store: holds the agenda, owns the appmessage calendar channel, and asks the phone for more whenever its turn on the face's cadence finds a poll due.
	calendar_store.h
	Active calendar store. It owns the appmessage calendar channel and its place on the shared cadence, so a face just hands it the rules (live / poll interval), optionally seeds it, then reads the events and subscribes for repaints. The phone data flows straight in and nobody wires it.
	health_store.c
	The active health store: reads the watch's health service and holds the numbers. It owns the service accessors too so it is the single point of truth for health.
	health_store.h
	Active health store. It subscribes to the watch's health service itself and holds the readings, so a face just hands it the rules, optionally seeds it, then reads the numbers back.
	location_store.c
	The active location store: holds the phone's coordinates and owns the appmessage coords channel.
	location_store.h
	Active location store. It owns the appmessage coords channel (the same phone geolocation the weather rides on), so a face hands it the rules, optionally seeds it, then reads lat/lon back. There's no poll timer. Coords arrive alongside weather.
	stock_store.c
	The active stock store: holds the quotes, owns the appmessage stock channel, and asks the phone for more whenever its turn on the face's cadence finds a poll due.
	stock_store.h
	Active stock store. It owns the appmessage stock channel and its place on the shared cadence, so a face just hands it the rules (live / poll interval), optionally seeds it, then reads the slots and subscribes for repaints. The phone data flows straight in and nobody wires it.
	store_cadence.c
	Holds the list of work the stores want run on the face's cadence.
	store_cadence.h
	The shared cadence the stores hang their periodic work on.
	store_fetch.c
	The fetch timing the polling stores share, in one copy every store links against.
	store_fetch.h
	The fetch timing the polling stores share: the one-shot catch-up, the cadence turn, and what an init or a reconfigure does to them.
	store_persist.c
	The save that skips an unchanged reading and the restore that feeds it, in one copy every store links against.
	store_persist.h
	Shared persist save and restore helpers for the stores.
	store_poll.c
	The polling decisions the weather, stock, and calendar stores share.
	store_poll.h
	Wall-clock deadlines for the stores that poll the phone.
	store_sum.c
	The checksum the stores compare before saving, in one copy every store links against.
	store_sum.h
	A checksum of a store's reading, so a reply that brings nothing new costs no flash write.
	system_store.c
	The active system store: holds the battery + bluetooth state and subscribes to the battery and connection services itself. The alarm is read through on demand.
	system_store.h
	Active system store: the watch's own battery, bluetooth and next-alarm state. It subscribes to the battery and connection services itself and buzzes on a bluetooth change through a policy the face installs (so the store never has to know about settings or buzzing).
	time_store.c
	The active time store: holds the current time and owns the tickers that update it.
	time_store.h
	Active time store. It owns the tickers (the minute tick, the swatch .beats AppTimer, and the hour tick) and swaps between them for the current cadence, so a face just hands it the rules and reads the time back.
	weather_store.c
	The active weather store: holds the readings, owns the appmessage weather channels, and asks the phone for more whenever its turn on the face's cadence finds a poll due.
	weather_store.h
	Active weather store. It owns the appmessage weather channels and its place on the shared cadence, so a face just hands it the rules (live / poll interval), optionally seeds it, then reads the values and subscribes for repaints. The phone data flows straight in and nobody wires it.
