Template: blocksy
Description: Dark-themed Blocksy child theme for =[LMX]= Thermal Reading — surface-temperature test data for flashlights on High and Turbo. Sibling of the LMX Deals child theme, restructured around measurement rather than commerce. Fully namespaced (lmxtr / _lmxtr_ / tr_) so it cannot collide with LMX Deals assets.

/* =============================================
   =[LMX]= THERMAL READING — DESIGN SYSTEM
   Sibling palette to LMX Deals: same dark base and
   amber family accent for brand continuity, plus a
   dedicated thermal ramp that only ever encodes
   temperature. Never use the ramp decoratively —
   the moment orange means "heading" it stops
   meaning "hot".
