The rain-intensity scale drops its two hyphenated compound labels for single
words and loses a tier, going from eight to seven:

  Trace / Light / Brisk / Typical / Heavy / Very Heavy / Extreme

- Light–Mod -> Brisk, Moderate -> Typical (renames only; classes unchanged).
- Mod–Heavy is merged up into Heavy, whose floor drops from the 75th to the 60th
  rain-day percentile, so Heavy now spans 60–90.
- The lightest tier (already the merged Very Light) is renamed Trace.

grading.py RAIN_BANDS and the frontend SCALE_RAIN mirror stay in lockstep, and
the detail-view ladder derives from the table so it follows automatically. The
now-unreferenced wet-6 colour token is kept so any day still cached under that
class renders until the derived store recomputes; the chart's percentile fan also
keeps it for a smooth gradient.
