/* =====================================================================
   /start/ v2 — sign-in / sign-up
   ---------------------------------------------------------------------
   Mirrors /home/'s .home-v2 visual language (dark, neon-cyan, Russo One
   headlines, JetBrains Mono terminal strip) but scoped to .start-v2 so
   it can't bleed into the rest of the site's chrome.

   Inputs need to live happily on a near-black surface. The site's base
   .form-control / .input-group styles assume white forms, so this file
   doesn't lean on them — every input/button gets a fresh sv2- variant.

   Form ids/names are intentionally unchanged from the legacy markup;
   the OTP / SMS / register JS in /start/index.php still wires up by id.
   ===================================================================== */

/* JetBrains Mono is named first in every monospace stack below (terminal
   strip, OTP digits, captcha, alt-links) but was never actually loaded —
   the strip silently fell back to Consolas on Windows and to whatever
   generic monospace a phone happens to ship. Loaded here so the page gets
   the face its own CSS asks for. */

   DAY / NIGHT
   ---------------------------------------------------------------------
   /start/ is the one page on the site every visitor sees before they are
   anybody, and it is routinely opened one-handed outdoors — a phone in
   sunlight is exactly where an ink-dark page stops being a mood and
   starts being a locked door. So it ships both themes, same as every
   module (see the day/night rule in CLAUDE.md).

   The preference is SITEWIDE: one `dmTheme` key in localStorage and an
   explicit `dm-light` / `dm-dark` class stamped on <html> pre-paint by
   renderThemeBoot() in the head. Someone who flips to light here is still
   in light when they land in /vault/ thirty seconds later. Because /start/
   has no module nav to hang the control on, the button is its own fixed
   pill in the top-right rather than a bar item.

   LIGHT THEME
   ---------------------------------------------------------------------
   A light theme is a DESIGN, not an inversion. The cyan that glows on ink
   (#7DD3FC) measures ~1.35:1 on white — as a link colour it is not dim,
   it is invisible. So the accent gets a separate paper value (#0369A1,
   5.9:1 on the card, and still 5.5:1 as white-on-fill for the button),
   which re-themes every link, prompt, border and badge in one line
   because they all read --sv2-cyan.

   What could NOT be retokenised is listed after: a handful of literal
   rgba(125,211,252,.0x) washes that are near-invisible on white, plus the
   pale hover fill and the inverted spinner, which only make sense on ink.
