News — Front-page Layout Builder
A newsroom-style front-page builder for a fictional broadsheet, pairing a left story queue of draggable cards with a right canvas of slot zones — Lead, two Secondary wells, an analysis Sidebar and an auto-composing Briefs strip. Drop a story into any slot and it renders live as editorial copy, with headline size, drop caps and pull quotes scaling to the slot; a desktop, tablet and mobile width toggle reflows the grid, and a Publish action confirms the edition with a toast. Vanilla JS, no libraries.

Seven in favor, four opposed, and with that the long-disputed waterfront district moved one step closer to a skyline it has been promised for the better part of a decade.",
"Supporters called it a generational investment in housing and transit. Opponents, many of them lifelong dockworkers, warned that the numbers behind the deal had never been fully explained to the people who would live with them longest.",
"What happens next depends less on the architecture than on the arithmetic. The bond package that underwrites the first phase must still clear a county review, and at least two of the yes votes were cast on the condition that affordability targets be written into the contract rather than the press release."

</html>Front-page Layout Builder
A two-panel newsroom tool for laying out the front page of The Meridian Ledger, a fictional broadsheet. The left rail is the story queue: a column of draggable cards, each colour-keyed by section — Politics, Business, Climate, Culture, Sport — with a serif headline, byline and read-time. The right side is the live front page itself, framed by a real masthead with volume line, dateline and price, and divided into slot zones: a tall Lead, two Secondary wells, an analysis Sidebar rail, and a five-column In Brief strip across the foot.
Drag any card onto a slot and it renders as a fully set article in place — and the typography scales to where it landed. The Lead gets a two-column justified body, a red drop cap and a pull quote; the Secondary wells set tighter; the Sidebar runs a narrow analysis column with its own rule; and the Briefs strip auto-composes a digest from whatever stories are not already on the page. Dropping a story that is already placed swaps it cleanly between slots, and every slot carries a remove control to vacate it. Cards are keyboard-operable too: focus one and press Enter to drop it into the next open slot.
A Desktop / Tablet / Mobile toggle reflows the grid so you can preview each edition without leaving the page, a layout meter tracks how full the front is, and Publish layout validates that a Lead exists before confirming the edition with a toast. Reset wipes back to a blank slate. All headlines, bylines, datelines and body copy are written as real-feeling editorial prose, and every interaction is plain vanilla JavaScript with no external libraries.
Illustrative UI only — masthead, headlines, bylines, and articles are fictional; not a real news publication.
