description	Generate curated marketing screenshots for README.md by stubbing watchface data in the emulator
disable-model-invocation	false

Generate the curated marketing screenshots shown in README.md. Read SCREENSHOTS.md for the full stubbing reference, then follow the steps below.

For each screenshot variant

Read the HTML comments in README.md above each <img> tag — they define the exact color, complication layout, weather values, date, and steps for that variant.

1. Stub settings in default_settings() (main.c)

Set s_settings.primary_color and all six complication slots to match the variant:

static void default_settings() {
  s_settings.primary_color = GColorPictonBlue;  // or GColorBlack, GColorPurpureus
  s_settings.mini_comp_left = MINI_COMP_STEPS;
  s_settings.mini_comp_middle = MINI_COMP_SUNRISE;
  s_settings.mini_comp_right = MINI_COMP_BATTERY;
  s_settings.bottom_comp_left = BOTTOM_COMP_HIGHLOW;
  s_settings.bottom_comp_primary = BOTTOM_COMP_WEATHER;
  s_settings.bottom_comp_right = BOTTOM_COMP_SUNSET;
}

Comment out persist_read_data(...) in load_settings() so stale emulator data does not override the defaults:

static void load_settings() {
  default_settings();
  // persist_read_data(SETTINGS_KEY, &s_settings, sizeof(s_settings));
}

2. Stub weather in load_weather() (main.c)

Replace the body with hardcoded values and set s_weather.loaded = true:

static void load_weather() {
  memset(&s_weather, 0, sizeof(s_weather));
  snprintf(s_weather.temp, sizeof(s_weather.temp), "78");
  snprintf(s_weather.high, sizeof(s_weather.high), "82");
  snprintf(s_weather.low, sizeof(s_weather.low), "65");
  snprintf(s_weather.city, sizeof(s_weather.city), "LA");
  snprintf(s_weather.sunset, sizeof(s_weather.sunset), "7:32");
  snprintf(s_weather.sunrise, sizeof(s_weather.sunrise), "6:15");
  s_weather.loaded = true;
}

3. Disable AppMessage in init() (main.c)

Comment out all five app_message_* lines. If you skip this, the JS companion fetches real weather on install and overwrites the stubs:

// app_message_register_inbox_received(inbox_received_callback);
// app_message_register_inbox_dropped(inbox_dropped_callback);
// app_message_register_outbox_failed(outbox_failed_callback);
// app_message_register_outbox_sent(outbox_sent_callback);
// app_message_open(256, 256);

4. Stub time in update_time() (main.c)

Replace the text_layer_set_text call with a hardcoded string. The emulator clock keeps ticking, so emu-set-time alone is unreliable:

text_layer_set_text(s_time_layer, "10:00");

5. Stub date/steps/month/year in update_status_buffer() (main.c)

Hardcode whichever buffers the active complications need. The emulator cannot change the date and returns 0 for steps:

snprintf(s_date_buffer, sizeof(s_date_buffer), "Sun 5");
snprintf(s_month_buffer, sizeof(s_month_buffer), "Apr");
snprintf(s_year_buffer, sizeof(s_year_buffer), "2026");
int steps = 23000; // instead of (int)health_service_sum_today(HealthMetricStepCount);

6. Build, install, and capture

pebble clean && pebble build
pebble install --emulator emery
pebble emu-battery --emulator emery --percent 100
pebble emu-bt-connection --emulator emery --connected yes
pebble screenshot --emulator emery

Move the resulting pebble_screenshot_*.png to screenshots/ with the correct name.

7. Verify

Read the saved screenshot and compare it against the existing one. Flag any differences.

8. Repeat or revert

Apply the next variant's stubs and repeat from step 1. After capturing all variants, revert main.c with git checkout src/c/main.c.
