/* Hallmark · pre-emit critique: P5 H4 E4 S5 R4 V4 · weakest: H, the record could flatten into one long list; led with the 500,000 plate and split the record into five named systems, four roles, six tool rows */
/* Hallmark · hero-review: fix · 4 findings · 4 resolved · headline now the claim, name on the foot line; board mass; black plate; single-line lead */
/* Hallmark · finish-review: subagent · 8 findings · 6 resolved 1 partial 1 unresolved · gap: the work index and roles still read as CV prose, not the site's voice */
/* Hallmark · post-review fixes: contact band padding no longer doubles, case head rules and scales, writing tags sit on the card floor, case body is a two-column grid · email is labelled "Email" */
/* Hallmark · content aligned to the updated resume · the record now matches the source */
/* Hallmark · reworded "500k+" to "~500,000 active users" · updated resume figure */
/* Hallmark · reworded "$8k" to "~$96K recurring annual savings" · updated resume figure */
/* Hallmark · reworded "$8,000" to "~$96K recurring annual savings" · updated resume figure */
/* Hallmark · dropped "30%" · not in the updated resume · the 5 new business areas figure replaces it */

/* Hallmark · reworded "100,000" to "high-throughput campaign and booking updates" · not in the updated resume */
/* Hallmark · reworded "8+" to "8 internal teams" · updated resume states eight teams */
/* Hallmark · dropped "10hours" · not in the updated resume · the cost-governance figure is ~$96K a year */
/* Hallmark · dropped #about, #philosophy, #experience, #certifications, #skills, #speaking from the nav · the nav keeps Work, Roles, Writing, Contact; every section, id and destination stays on the page */
/* Hallmark · reworded "national health platform—delivering" to "national health platform, delivering" · 19 names the dash */
/* Hallmark · reworded "mahendra yadav" to "built to hold under load." · the claim leads the hero, the name moves to the foot line */
/* Hallmark · reworded "engineering philosophy" to "how i work" · plain nouns, the section is four rows */
/* Hallmark · reworded "systems & platform case studies" to "selected systems" · the section is one opened case and an index */
/* Hallmark · reworded "national health data platform & azure databricks architecture" to "national health data platform" · the stack line carries the architecture */
/* Hallmark · reworded "work history" to "roles" · four roles, one row each */
/* Hallmark · reworded "engineering notes & writing" to "writing & speaking" · the talks fold into the writing section */
/* Hallmark · reworded "cloud certifications" to "certifications" · the certs sit beside the skills under Toolkit */
/* Hallmark · reworded "speaking & technical leadership" to "speaking & community" · the talks are community work, not leadership */
/* Hallmark · reworded "design for failure, operate for clarity" to "i design for failure" · first person, the hero's plain voice */
/* Hallmark · reworded "governance is a feature, not friction" to "i treat governance as the product" · first person, the platform is shared */
/* Hallmark · reworded "cost is an architectural property" to "i price cost into the design" · first person, cost is a design input */
/* Hallmark · reworded "boring primitives, deliberately applied" to "i keep novelty off the critical path" · first person, the stack stays plain */
/* Hallmark · reworded "userimack.png" to "assets/mahendra-yadav.png" · the portrait is served locally, not hotlinked from GitHub */
