/* pra.toolforge.ai — page layer over toolforge-ds.css.
 *
 * Every value here comes from the design system: the 4px scale (4 8 12 16 24 32 48 64),
 * the four border widths (1 hairline, 2 control, 3 rule, 6 accent), and the token colours.
 * No radius, no shadow, one red action (the Search button), one yellow band at the end.
 *
 * Chart ink: bars and heat cells are Ink over a Line or Canvas track. Red stays reserved
 * for the single primary action, so no chart element is red.
