/** * Insulated vs. Non-Insulated Materials Investigation - styles. * * Visual language matches the Thermal Energy Lab (Space Grotesk display * type + Inter body, the same paper/ink/accent palette shape, .{prefix}-btn * pill controls, .{prefix}-panel cards) under this lab's own "ins-" prefix - * a page-local palette per the house lab convention (see thermal-energy.css) * rather than a shared stylesheet, since each standalone lab view renders * its own document. * * Layout thesis: unlike Thermal Energy's single always-running apparatus, * this lab's "experiment" IS the sequence of discrete timed trials, so the * chart, results table, and ranking are three stacked full-width panels * (no side rail) - there is no single dominant visual to give a wide main * column to. The material picker + controls sit in one setup bar above all * three, matching Thermal Energy's sample bar. * * WCAG 2.1 AA: 0.75rem minimum font size, 44px touch targets on primary * controls, every state (best/worst insulator, which material a line/row * belongs to) is labeled in text, never conveyed by color alone. */ :root { --bg: #eef3fb;
