/* Brackenhouse Accountants — first-party accountancy template (S115).
   All imagery is authored CSS. No media, fonts, icons, embeds, CDNs, analytics or tracking.

   Voice: ESTABLISHED AND PRECISE. Deep navy and brass gold on ivory, a serif display over a sans
   body, CRISP 8px radii and tight lines — the traditional, trustworthy register a finance firm
   trades on, and unlike the rest of the library (haulwell's heavy indigo caps, brightloom's airy
   cyan, fernwild's romantic rose serif).

   This template carries TWO client-side tools (tools.js): a PAYE take-home calculator (illustrative
   2024/25 England & Wales bands) and a LIVE self-assessment deadline countdown computed from the
   date. No API, no key, no network — figures are illustrative and framed as an estimate. */

/* --- Touch targets ------------------------------------------------ S116
   A standalone control needs 44x44 CSS px (Apple HIG; WCAG 2.5.5 AAA, and 2.5.8 AA
   sets a 24px floor). The S116 polish pass measured the header phone link at 23px
   and the Menu button at 35px on a 390px viewport, on every template in the library.
   On a trades site the phone number IS the conversion — it was rendering at half the
   required size at exactly the width most visitors arrive on.

   Layout only, no colour, so this block is copy-paste identical across every palette
   in the library. Inline links inside prose are deliberately NOT touched: both WCAG
   target-size rules exempt them, and padding them out would wreck the body copy. */
