VERSION 7.0 CHANGES (2026-04-02):
----------------------------------
MAJOR UPGRADE: Rolling 48-Hour Logic & Midnight Bridge
- Added Dual-Buffer NVS: Stores "Today" and "Tomorrow" independently.
- Midnight Bridge: At exactly 00:00:00, "Tomorrow" data automatically becomes "Today",
eliminating the 1AM/2AM UTC offset fetch delay.
- Seamless 48H Scrolling: If next-day data is available, the button allows
scrolling up to 47 hours ahead.
- Visual Indicators: Future hours are marked with "HH:>>" to distinguish
from today's "HH:00".
- Smart Fetching: Automatically looks for tomorrow's data after 14:00 local time.
