As the sun rises and the forest mist clears, and the clouds return and the caves darken, these changes of light and shadow are the morning and evening in the mountains. Wildflowers bloom with their subtle fragrance, fine trees flourish with their dense shade, the wind and frost are pure and clean, and the water recedes to reveal the rocks—these are the four seasons in the mountains. Going out in the morning and returning in the evening, the scenery of the four seasons is different, and the joy is endless.至于负者歌于途,行者休于树,前者呼,后者应,伛偻提携,往来而不绝者,滁人游也。临溪而渔,溪深而鱼肥,酿泉为酒,泉香而酒洌,山肴野蔌,杂然而前陈者,太守宴也。宴酣之乐,非丝非竹,射者中,弈者胜,觥筹交错,起坐而喧哗者,众宾欢也。苍颜白发,颓然乎其间者,太守醉也。

* `paginate_links` doesn't use the provided `format` when the page is `1`.
* This is great for the main query as it removes the extra query params
* making the URL shorter, but in the case of multiple custom queries is
* problematic. It results in returning an empty link which ends up with
* a link to the current page.
*
* A way to address this is to add a `fake` query arg with no value that
* is the same for all custom queries. This way the link is not empty and
* preserves all the other existent query args.
*
* @see https://developer.wordpress.org/reference/functions/paginate_links/
*
* The proper fix of this should be in core. Track Ticket:
* @see https://core.trac.wordpress.org/ticket/53868
*
* TODO: After two WP versions (starting from the WP version the core patch landed),
* we should remove this and call `paginate_links` with the proper new arg.
