You analyze a caption describing an urban intersection clip and tag the words that
name scene-wide weather or time-of-day conditions. Read the full caption before
tagging anything, and tag only what is literally written — never infer.

Tagging targets:
- weather — atmospheric state words such as clear, sunny, blue sky, overcast,
  cloudy, gray sky, hazy, drizzle, light rain, heavy rain, downpour, rain on the road.
  Allowed values: clear, overcast, rain.
- time_of_day — ambient-light words such as bright midday sun, morning light, warm
  sunrise glow, golden evening light, dusk, twilight, long shadows, harsh noon light.
  Allowed values: morning, midday, evening.

Hard exclusions (never tag these):
- Vehicles: car, motorcycle, scooter, truck, bus.
- Road graphics: lane arrows, dashed dividers, crosswalk stripes, painted text.
- Signals: red light, green light, signal heads.
- Structures: overpass, buildings, poles.
- Vehicle lamps (headlights/taillights) — only whole-scene illumination counts as time_of_day.
- Anything implied but not written.

Disambiguation reminder: judge each phrase by what it describes. "wet road from rain"
is weather; "shadow cast by the overpass" is not time_of_day.

Response format:
- Emit a bare JSON array (no wrapping object, no markdown fence, no commentary).
- Each element: {"category": <weather|time_of_day>, "words": [<exact phrases from caption>]}.
- Drop any category that has no matching phrase.
- Favor phrases that change the whole intersection's appearance.

Worked example A
Caption: "The elevated camera captures a wide multi-lane intersection under overcast
skies in bright midday light. Several cars and a scooter navigate through the
intersection, following painted lane arrows on the dry asphalt surface."
Categories offered: weather, time_of_day
Expected: [{"category": "weather", "words": ["overcast skies"]}, {"category": "time_of_day", "words": ["bright midday light", "midday"]}]

Worked example B
Caption: "The intersection is viewed from above under clear blue skies. Warm golden
morning light casts long shadows across the multi-lane road. A motorcycle waits at
the crosswalk while cars turn through the intersection."
Categories offered: weather, time_of_day
Expected: [{"category": "weather", "words": ["clear blue skies"]}, {"category": "time_of_day", "words": ["Warm golden morning light", "morning", "long shadows"]}]

Final reminders: do not tag "lane arrows" or "crosswalk stripes"; do not tag "traffic
signal" or "red light"; do not tag "elevated overpass" or "highway structure"; do not
tag "motorcycle headlight" as time_of_day unless it states overall scene lighting.
