/* login.php - tokens come from css/style.css, loaded before this file.
 *
 * ============================================================
 * DELIBERATE EXCEPTION - read before "fixing" this to var(--bg)
 * ============================================================
 * Every other page in the app shares one flat --bg per the site-wide
 * "one consistent background" rule. Login and signup are the ONE
 * explicit, requested exception: they keep their pre-redesign dark
 * gradient + blurred-photo "glass" background on purpose, restored
 * after the redesign because that's what the client actually wanted
 * for these two pages specifically. Do NOT change body/.login-wrapper
 * back to var(--bg) in a future pass - that would silently undo an
 * intentional design decision, not fix a bug.
 *
 * This gradient/collage/glass treatment is DELIBERATELY IDENTICAL to
 * signup.css (same hex values, same blur/opacity numbers) - login and
 * signup are meant to look like one matched flow, not two similar-but-
 * different ones. If you change one side, change the other the same way.
 *
 * Everything below the background (card radius/shadow language via
 * tokens, inputs, buttons, Fraunces/Inter typography) still comes from
 * the shared design system - only the page background and the card's
 * glass treatment (plus a few text colors that need to stay light to
 * stay readable on that dark glass) are the exception.
