   ONTARIO PHYSICS ONLINE TUITION — PREMIUM STYLESHEET
   Concept: "The Control Panel" — graphite/PCB surface, phosphor-green
   CRT accent, circuit-trace structure. Deliberately distinct from the
   Mathematics page's warm drafting-table look: Physics gets a dark,
   instrument-panel identity instead.

   SCOPING NOTE
   Every rule is anchored to this page's own classes via
   [class*="ontario-physics-"] (section wrappers) or [class*="physics-"]
   (card/grid/note components). No bare tag or utility-class .elementor-12694 .elementor-element.elementor-element-bda9a63s
   (<a>, <section>, .container, .btn) are left unscoped, and alternating
   section backgrounds are assigned by explicit class name rather than
   :nth-of-type, so nothing here can bleed into a header, footer, or any
   other page. No HTML changes required.
