/* estimate page — WhatsApp unlock line */
/* v79 · This box used to be joined on the estimate page by a SECOND element
   carrying the same class but no icon, so the flex gap collapsed and the two
   rendered with different alignment and weight — the "different colours"
   Brendan reported. The calculator now lives on the page instead of arriving
   through a URL, so there is only ever one of these. Tightened while it was
   open: a left gold rule instead of a full box, and the icon optically centred
   on the first line rather than nudged with a magic number. */
/* v79.2 · THE REAL BUG, not a taste problem. This is display:flex, so EVERY
   direct child becomes a flex item — including the <strong>. The line was
   therefore laid out as four columns: [icon] [Your] [free instant quote] [comes
   back with…], each separated by the gap, which is why "free instant quote"
   rendered as its own narrow wrapped column with space either side. Wrapping
   the text in one .unlock-txt span makes it two items — icon and text — and the
   sentence flows as a sentence. align-items is flex-start with the icon nudged
   to sit on the first line's optical centre; centring it looked wrong the moment
   the text wrapped to two lines. */
