/*
 * GymDesh — পণ্যের নিজের পাতার সাজ: "০১ সংকেত" (Signal)
 * ======================================================================
 *
 * এটি Sarotia-র দোকান, কোনো জিমের সাইট নয় — তাই রঙ সবসময় পণ্যের
 * নিজের সংকেত-বেগুনি, আর নাম Schibsted Grotesk-এ (পাশে বেগুনি ●)।
 * জিমের সাইটের সাজ (site.css) থেকে আলাদা ফাইল: কোনো জিমের রঙ বা
 * জিমের পাতার নিয়ম এখানে আসে না, এখানকার বদলও জিমের সাইটে যায় না।
 *
 * নমুনা: docs/themes/sanket.html; বিবরণ: docs/themes/spec/sanket.json →
 * screens.product_page। সমতল — ছায়া, ঝাপসা, গ্লো নেই; কোণ ১০/১৪px।
 * কোনো JavaScript নেই: মাসিক/বার্ষিক সুইচ লুকানো radio দিয়ে, ফোনের
 * মেনু `:target` দিয়ে (লিংকে চাপলে নিজেই বন্ধ হয়)।
 *
 * বাংলার নিয়ম: `letter-spacing`/`uppercase` নয়; বহু-লাইনের শিরোনামে
 * line-height ≥ ১.৪ ও `text-wrap: balance`।
