Functions
Box	vbox (ObjectView parent)

	Creates a horizontal flex container (`LV_FLEX_FLOW_ROW`) sized to its content.

Detailed Description

C++ abstractions for the LVGL embedded GUI library.

This namespace provides:

LvglGuard — RAII lock for thread-safe LVGL access.
ObjectView — lightweight, non-owning wrapper around lv_obj_t*.
CRTP mixin templates (ObjectMixin, EventMixin, StyleMixin) that add fluent setter chains to concrete widget types.
Style — RAII wrapper for lv_style_t.
State<T> — reactive integer state backed by the LVGL observer (requires LV_USE_OBSERVER).
Concrete widget wrappers: Label, Bar, Box.
Layout helper functions: vbox(), hbox().
Component<Derived> — CRTP base for reusable UI components.

Note: All methods that modify LVGL objects must be called from the LVGL task context or while holding the LvglGuard lock.
