/* ───────────────────────────────────────────────────────────────────────────── Fulcrum — marketing site stylesheet. Hand-rolled (no Tailwind build step), speaking the same design language as the rest of the Renkara marketing estate (packed.renkara.com is the closest sibling): HSL-triplet custom properties, a `.dark` class on , one --brand scale every component reads through, and a card helper. Fulcrum's product accent is Indigo per the Renkara brand guidelines; everything else inherits the shared navy/slate scale. Contrast: every pairing below clears WCAG 2.1 AA (4.5:1 body, 3:1 large text and UI) on BOTH themes. The indigo scale is split for that reason: --brand is decorative, --brand-text is the AA-safe text/fill color on the page and card grounds, --brand-on-tint is the AA-safe color on the tint. ───────────────────────────────────────────────────────────────────────── */ :root { --background: 210 33% 98%;
