fix(docs): stop hiding the footer sidebar collapse button

[patcapulong]

The collapse button in the docs sidebar footer does nothing on production. The icon renders, but clicking it has no effect.

Our "hide sidebar controls" rule in mintlify/style.css includes [class*="sidebar"] button[class*="collapse"], which was meant for Mintlify's native collapse button. Mintlify's hosted renderer now puts w-(--sidebar-width,19rem) on nav#sidebar-content, so that selector matches every button in the sidebar whose class contains "collapse", including our own .ls-nav-collapse-btn. The rule sets display: none !important on our click target. The icon still shows because it is drawn by pseudo-elements on the theme switcher, so clicks fall through to the footer div.

• Exempt .ls-nav-collapse-btn from that one selector with :not(.ls-nav-collapse-btn). The other hide rules are unchanged.

Test plan

• On docs.lightspark.com, confirmed the button computes to display: none with a 0×0 box and is absent from the accessibility tree.
• Applied the same selector change to the live stylesheet in the browser and clicked the footer icon with a real mouse. The sidebar collapsed to the 48px rail and ls-nav-collapsed was saved to localStorage.

Faraday review

fastpass advisory - comment-only, never blocks a merge. To retire a finding, either fix it or reply explaining why it is wrong: a rebuttal gets an agree or disagree answer on the thread, and if you reply again after a disagreement we concede. Acknowledging it ("will fix") or resolving the thread does not retire it on its own. This comment is edited in place every round; inline findings still post as new comments each round.

Faraday score: 5/5 (clean) - 5 nothing blocking open | 4 non-blocking only | 3 one blocking open | 2 two | 1 a P0 or 3+ blocking; never drops without a new blocker

🦕 Congratulations @patcapulong - you caught a Shantungosaurus! (common)

Shantungosaurus was one of the largest hadrosaurs known, reaching lengths rivaling some of the biggest carnivorous dinosaurs. Its fossils come from Shandong Province in China, which gives the genus its name.
