The footer literally renders {{Year}} as the copyright year.
The current opticshop-aber.co.uk footer displays "(c) The Optic Shop {{Year}}. All Rights Reserved." The raw template variable has never been wired up to a real date. It is in the live HTML twice. Every patient who scrolls to the bottom of the homepage sees the unresolved placeholder. The same footer is on every page of the site.
For a premium independent optometry practice in the 25th year of trading, an exposed templating placeholder reads as "the website is not maintained". A patient comparing The Optic Shop against Specsavers Abergavenny on a Sunday evening, with hundred-thousand-pound diagnostic kit on the technology page above and “{{Year}}” in the footer below, has to choose between the two signals. The footer signal wins because templating bugs are not what a serious practice ships.
After rebuild: the copyright year is generated from new Date().getFullYear() at build time, so every page reads "(c) The Optic Shop 2026" today, "(c) The Optic Shop 2027" on 1 January, and never again. Same fix touches every page that uses the footer partial. Five minutes of build setup, twenty-six years of correct dates.
