fix(brand): the logo, the typeface and the palette are HDFC's actual ones

The console was wearing an approximation of the bank. Everything here was
read off HDFC Bank's own production assets instead.

The mark was inside out. It had been drawn as a blue square with a red
square inset; HDFC's is the reverse — a red ground, a white channel cross
splitting it into four corner blocks, and a small blue square at the
centre. Every coordinate now comes verbatim from the SVG the bank serves
in its own site header, including the "HDFC BANK" wordmark outlines, so
the lockup is the bank's rather than a redrawing of it. The favicon in
index.html carried the same inversion and is fixed with the same numbers.

Open Sans replaces the Segoe UI stack. hdfcbank.com preloads OpenSans
Regular / SemiBold / Bold / ExtraBold and sets its whole site in it. It is
self-hosted through @fontsource-variable/open-sans rather than pulled from
a CDN, for the reason the API URL is read at runtime: this build gets
promoted between environments and dropped behind bank proxies, and a font
that sometimes fails to arrive is a product that sometimes looks like
someone else's.

The header stops being a navy band. HDFC puts the full lockup on a light
ground on every one of its own digital surfaces, and a navy header made
the real logo unusable — the lockup's own blue bar would have dissolved
into it. The blue now does its work as the rule under the header, the
active queue and the primary button, which is how the bank uses it. The
lockup's 3px white keyline is the bank's own, so it sits correctly on the
panel in dark mode too and no reversed variant is needed.

Palette, grounded rather than invented: the page canvas is #F0F6FB, the
tint hdfcbank.com uses behind content; the good/ tokens sit on the hue of
the bank's #00B947 instead of a generic emerald, darkened to #00713D
because #00B947 is 2.6:1 on white and unreadable as a label. The two brand
hexes were already right and are unchanged.

Also closes three AA failures the palette claimed it did not have —
--color-faint in light, and --color-faint / --color-brand in dark, each
below 4.5:1 on --color-panel3. White on --color-signal (4.31:1) is left
alone knowingly: darkening HDFC red for the Decline button would have made
it a different red from the logo beside it.

+ * served in the header of hdfcbank.com:
+ *
+ *   https://s7ap1.scene7.com/is/content/hdfcbankPWS/hdfc-bank-logo
+ *
+ * Nothing here is drawn by eye. That matters because the mark had been drawn by

+ * real mark is the other way round — a RED ground, a white channel cross that
+ * splits it into four corner blocks, and a small BLUE square at the centre.
+ * Getting that backwards is the kind of thing a client notices in the first
+ * five seconds of a demo.
+ *
+ * The mark, normalised to a 40x40 grid, is:
+ *
+ *   red    0,0   40x40    the ground
+ *   white  7,7   26x26    the inner square
+ *   white  18,0   4x40    the vertical channel
+ *   white  0,18  40x4     the horizontal channel
+ *   blue   14,14 12x12    the centre
+ *
+ * THE TWO COLOURS ARE FIXED AND ARE NOT THEME TOKENS. A logo does not restyle
+ * itself for dark mode: HDFC red is #ED232A and HDFC blue is #004C8F on every
+ * surface, in every theme, forever. The white is real white for the same
+ * reason. This is the one file in the app allowed to hold literal colours, and
+ * the reason it is allowed is that these are not design decisions.
+ *
+ * The full lockup carries a 3px white keyline, exactly as the bank's asset
+ * does. That keyline is what lets the logo sit on a coloured ground without
+ * the blue bar bleeding into it — so the lockup is safe on the panel in either
+ * theme, and no reversed variant is needed.
