/*
  The approved footer layer, ported rule for rule from the reference build's global stylesheet
  (ndic-reference/css/styles.css:4784-4930, plus the one responsive rule at :518).

  WHY IT IS A FILE AND NOT PART OF styles.css. These rules live in the reference's global sheet, but
  ours is not byte-identical to it and is 8,296 lines with a history of a single unclosed at-rule
  gating 92% of the file. Keeping the approved footer here makes it inspectable and diffable against
  the reference the way home.css, about.css and px-shared.css already are, and none of these eleven
  class names existed anywhere in this build, so nothing collides.

  ONE DEVIATION FROM THE SOURCE. The reference writes the pattern as `url("../assets/images/...")`,
  correct from `css/styles.css`. This file sits one directory deeper, so the URL is absolute instead
  of `../../`. Same file, and it cannot break if this stylesheet is ever moved again.

  `.footer-shell .ndic-container { max-width: none }` is deliberate and is the reason the footer runs
  wider than the rest of the site. It is the approved behaviour, and it needs stating because this
  build adopted `--container-max: 1440px` site-wide on 2026-08-05 — without this override the footer
  would stop at 1440px, which the approved design does not do. Specificity (0,2,0 over 0,1,0) means
  it wins without !important.

  The button is always in the layout and only faded, so `pointer-events: none` in the hidden state
  is not cosmetic: without it an invisible 46px target sits over the bottom-right of every page and
  swallows clicks meant for whatever is underneath.
