/* === DaCucina login screen — centred slab (approved concept 2026-09-24) — scoped to .dc-login only ===
   The existing #login-screen container carries .dc-login; the ORIGINAL form (ids username / password / login-btn / login-error,
   handlers in app.js) is kept untouched inside .dc-login__form. Nothing here targets other screens.
   Layers: .dc-login__scene = pointer depth (translate) · .dc-login__scene-img = entrance zoom (scale) · vignette · drafting grid ·
   corner marks · title block / stamp / scale bar / tagline in the margins · .dc-login__center (flex centring, scrolls on short
   viewports) · .dc-login__panel = the slab (LED ring, inner frame, top bronze line, floor shadow via ::after).
   Motion: entrance zoom + slab rise + 100ms stagger; LED light travelling around the frame; depth by pointer (JS).
   prefers-reduced-motion / phones: no motion (static ring), form usable from the first frame. */
