/* Hallmark · pre-emit critique: P4 H4 E4 S4 R4 V3 · weakest: V, replaced repeated card grids with side titles, open rows, a preparation strip and unboxed pricing */
/* Hallmark · user constraint: all wording, punctuation and section order are retained; colour icons explicitly requested. */
/* Hallmark · answered F5 · colour icon tiles are explicitly requested to distinguish SMS, identity and payment */
/* Hallmark · waive 3 · the account section retains three preparations from the brief · SMS, payment and identity use open columns without card borders */
/* Hallmark · waive 44c · the Claude hero fits the 1280x800 fold · forcing a full viewport would add empty space below the four requested bullets */
/* Hallmark · waive 49b · source titles are retained verbatim · Claude documentation links may occupy two readable lines on narrow phones */
/* Hallmark · waive 59 · original section sequence is retained · compact transitions around Claude pricing and preorder avoid redundant whitespace */
/* Hallmark · waive 77 · the devices section is an intentional short statement · no invented content or image may be added to the user's Claude copy */
/* Hallmark · user override 63 · middle dots in the supplied hardware specifications are retained under the explicit verbatim-copy instruction */
/* Hallmark · finish-review: subagent · 2 suggestions declined due to explicit user constraints: no hero price, plan actions after full included-services list */
