/* The Testing Academy — Playwright Practice
Shared theme: ChatGPT-inspired neutral workspace, light + dark, plus the
collapsible sidebar shell used on every page.

NOTE: Google Fonts are loaded via in each
page's (with preconnect) — not via @import here — so the
font request doesn't block CSS parsing in a 3-deep chain. */
