 * Section 7 of the Superannuation page: a centred header over a stack of wide
 * white cards. Every card pins at the same offset, so the next one slides up and
 * covers the one before it completely, fading it out as it goes — the
 * sticky-stacking treatment drawn part-way through in Figma 2104:10612.
 *
 * Depends on `novabp-tax-base` for tokens and the header primitives.
 *
 * Figma reference: node 2088:4917 (card 2101:9111 / 2104:11244, stacked state
 * 2104:10612)
