56de2d0 — fix(template): reduce E2E failures 40→6 — SEO meta, heading order, button attrs, nav submenu

axe-core heading-order doesn’t scope by <section> — treats all headings as a flat document sequence. H1 in one section + H3 in another = violation even with HTML5 sectioning.
CSS max-height animation breaks Playwright visibility — max-height: 0 → 500px transition causes element height=0 at animation start; Playwright toBeVisible() fails.
Nav menu opacity transition affects children — waitForSelector('.open') resolves early when element is at opacity:0; child links inherit near-zero opacity. Must waitForFunction on opacity > 0.99.
class*="outline" false matches — Tailwind’s focus-visible:outline-none is in every button’s class string. Add data-variant attribute for precise targeting.
position: fixed containers unscrollable — Playwright scrollIntoViewIfNeeded() cannot scroll fixed containers. Use toBeAttached() instead of toBeVisible() for links inside fixed nav.

Test	Root Cause
modal.spec.ts:33, :248	Modal Alpine.js wiring broken (pre-existing)
form-fields.spec.ts:325	Tab order through form fields (pre-existing)
form-fields.spec.ts:234	Flaky networkidle timeout on /components
dark-mode.spec.ts:64	SmartDebt green contrast 1.95:1 in dark mode (design token issue)
performance/baseline.spec.ts:24	Unsplash CDN timeout under test conditions
