/* ==========================================================================
   Interface upgrade — the components the redesigned pages introduced
   ==========================================================================

   Loaded LAST so it can settle anything the older sheets still assert. What is
   here is only what the new markup needs: the homepage lead, the four-story
   section block, the listing card, breadcrumbs, the pager and the article
   frame. Everything else — masthead, footer, ticker, update rail, bottom bar,
   push card — was already redesigned and is left alone.

   ── THE COLOUR RULE ───────────────────────────────────────────────────────
   Two hues doing two different jobs:

       red   (--sp-red)   URGENCY   breaking, live, the brand mark
       blue  (--sp-blue)  STRUCTURE sections, links, breadcrumbs, pager, nav

   The red is sampled from the NST Bihar wordmark. The blue is NOT in the logo
   — there is not one blue pixel in it — and is here on purpose; the reasoning
   is in the palette block in globals.css.

   A news page needs two signal channels. The reason news portals end up
   looking like alarm panels is that they run both through one red: when the
   section rule, the timestamp, the navigation and the BREAKING flag are all
   the same colour, none of them is a flag any more.

   ── THE TYPE RULE ─────────────────────────────────────────────────────────
   Devanagari sits taller than Latin at the same font-size and its matras need
   room above and below, so every line-height here is a step looser than the
   equivalent Latin value would be. Headlines never go below 1.35.

 * TWO FILES, ONE SLOT.

 * chooses; a JavaScript swap would show the wrong one until it ran, which on a
 * masthead is the first thing the reader sees.
 *
 * ── WHY THE SELECTORS CARRY `img` ─────────────────────────────────────────
 * The first version of this was `.sp-logo-dark { display: none }`, and BOTH
 * logos rendered. `header.css` already styles `.sp-head-logo img`, which is a
 * class plus an element — specificity 0-1-1 — and it sets `display`. A bare
 * `.sp-logo-dark` is 0-1-0 and loses, so the "hidden" one was never hidden.
 *
 * Qualifying these with `img` makes them 0-1-1 as well, and since this sheet
 * loads last the later rule wins. The dark-mode pair is 0-2-1 and wins
 * outright. Nothing here sets height or width: `header.css` owns the masthead
 * sizing and there is no reason for two files to argue about it.
